ATTENTION
You must configure the SIP IP Phones with the CS 1000 SIPL UEXT Universal Extension SIPL subtype, which provides a line appearance to the SIP IP Phones.
The following figure illustrates the architecture of the SIP Line Service.
Figure 1 SIP Line architecture
This figure demonstrates the complete SIP Line architecture of CS 1000 and this architecture is implemented in phases. The SIP Line Gateway (SLG) is the SIP Line signaling gateway, which communicates between the CS 1000 Call Server (CS) and the SIP side of the signaling. The SIP Line Gateway (SLG) serves as a SIP Registrar and a SIP Proxy server to users. The SLG uses voice signaling messages to communicate internally with the Call Server.

A Call Server hosts each SIP line instance. This means each SIPL UEXT represents one SIP IP Phone. The SIP IP Phones supported by CS 1000 behave either as a regular Universal Extensions or as a SIP Line. The behavior of the IP Phone and the invocation of the SIP Line Service depends on the configuration of SIP Line in LD 11.
If you enter SIPN (SIP Line for Nortel IP Phones) at the UXTY prompt, then the phones behave like regular Universal Extensions. Only trunk features are provided to such IP Phones. If you enter SIPL (SIP Line) at the UXTY prompt and 1 0 0 0 at the Maximum Client Count Limit (MCCL) prompt, then the phones behave as a SIP Line.
The following steps describe the call flow between Line A (on System 1) and Line C (on System 2):
Nortel Communication Server 1000 SIP Line Fundamentals NN43001-508 02.01 4 June 2010

1. Line A dials 63331155. A SIP INVITE message is sent to the SIP Line
Gateway (SLG), and then the SLG authenticates the originating SIP Line.
2. The SLG presents the call to the CS 1000 Call Server (that is, CS 1000
CS on System 1).
3. The Call Server applies all line call origination rules to the call as
indicated in the Universal Extensions (SIPL UExt-A) settings.
4. Based on the dialing plan rules (for example, LOC 333), the call is
routed to the remote system. The route used to reach the far-end depends on the dialing plan configuration. It can be either an IP VTRK (for example, H.323, SIP) or TDM trunks (for example, PRI, DTI). In this example, SIP trunk is used.
The SIPL UExt-A must have the required access privileges for the
call to be routed.
5. The call is routed to the target system. In this call flow example, the
call is routed using the SIP Proxy Server. However, the Gatekeeper or direct TDM trunk connections can be used. (How a call is routed depends on the customers configuration.)
6. The Call Server tries to terminate the call on the SIPL UExt-C. It
applies all line termination features as indicated in the SIPL UExt-C settings. An attempt to terminate the call on a SIPL UEXT triggers a SIP call using the SIP Line route associated with the user.
7. The call is delivered to the SLG associated with the SIP Line route. 8. Based on the existing registration record of Line C, the SLG routes the
call towards Line C.
Deployment models
Some sample SIP Line deployment models are shown in the following sections.

The Nortel CP PM and CP DC platforms are circuit cards hosted in Media Gateway slots in CS 1000E systems or in slots of Universal Equipment Modules (UEM) in CS 1000M SG and CS 1000M MG systems. The CP MG platform is a circuit card and is hosted in slot 0 of a Media Gateway in CS 1000E systems. The other platforms are commercial off-the-shelf (COTS) servers. For more information about the platforms, and instructions to install, see Linux Platform Base and Applications Installation and Commissioning (NN43001-315). The following table outlines the minimum requirements for all supported platform types:

The minimum requirement for the Removable Media Device Compact Flash (RMD CF) card (as installed media) is 1 GB.
ATTENTION
In CS 1000 Release 7.0, you can configure the SIP Line Service with the Line Terminal Proxy Server (LTPS) using the same DCH or with other Virtual Trunk applications (such as the SIP Gateway or H.323 Gateway).
By default, support for the G.711 codec must exist at both ends of a call. Unrecognized codecs (including video codecs) are forwarded to far end through the Session Description Protocol Transparency (SDP-T) feature. The SIP Line Gateway sends the codec list of the offerer (in order of preference) and the receiver selects one common codec based on its list of preferred codecs. The receiver always performs the codec selection and selects one common codec based on the Best Bandwidth selection mechanism. If a specific payload size is configured different from the default payload size, a packet time (ptime) is included in the offer. In this version of SDP, only one ptime is available for each codec. If no ptime is included in the SDP, the default payload size is used.

For more information about codec selection, see IP Peer Networking Installation and Commissioning (NN43001-313).
Bandwidth management
The SIP Line Service is incorporated in the existing Bandwidth Management (BWM) functionality on the Call Server where the devices in the network belong to some logically defined zone (usually the geographic location of the device). Several aspects of interworking between the devices (and between the zones) are managed by the Bandwidth Management feature such as the following:
bandwidth limits and current usage preferred codec selection alternate routes decision
The following sections describe bandwidth management operation for SIP Line. Bandwidth Management configuration for SIP Line is divided into the following two steps:
1. Planning zone setup for SIP Line IP Phones and configuration using
LD 117 utilities (page 28)
2. Configuring SIP Line IP Phones with a SIPL zone (page 29) Planning zone setup for SIP Line IP Phones and conguration using LD 117 utilities
Before SIP Line IP Phones are configured in a bandwidth zone, the zone must be represented in the zone table. LD 117 maintains the zone table configuration. The system administrator must select the zone number to use for SIP Line IP Phones. The SIP Line zone must not be the same as VTRK zone. You must configure the SIP Line zone with an intrazone and interzone policy, which is either Best Quality (BQ) or Best Bandwidth (BB). Also, based on the network characteristics, you must configure the bandwidth limits for intrazone (Local Area Network [LAN]) and interzone (Wide Area Network [WAN]) calls. Example: >ld 117 >new zone 1 1000000 BQ 1000000 BB

Bandwidth management
29
After you add the zone in the zone table and you configure all parameters, use LD 43 to issue the Equipment Data Dump (EDD) command. This command updates the zone.db file with recent changes.
Zone operation
Calls that involve a SIPL UEXT are calculated against the respective zone configuration. This zone operation is the same as for other telephone types (for example, UNIStim telephones).

Copyright 2009-2010 Nortel Networks. All Rights Reserved.
Codec negotiation
Only supported codecs are used in the calculations in bandwidth management modules. The SIP Line IP Phones must have at least one supported codec configured. SIP Line IP Phones can negotiate other codecs (those not listed in the supported codec list) in the following scenarios:
SIP Line-to-SIP Line audio and video call SIP Line-to-Third-party SIP entity audio and video calls
If an unsupported codec is negotiated for a SIP Line call, then bandwidth management ignores the unsupported codec and tries to select a supported codec (based on the codec lists). Bandwidth management calculations are inaccurate in such scenarios. For deployments where accurate bandwidth management calculation is more important than the codec selection, you must configure the SIP IP Phones with the codecs supported by CS 1000.
Codec selection
Two models of codec selection are available for Bandwidth Management:
Local codec selectionThe codec is selected based on the policies of the zones involved. The selected policy (Best Bandwidth [BB] or Best Quality [BQ]) determines the order in the codec list and the first codec in the list is chosen. For example:
Zone 1: Intrazone policy is BQ and interzone policy is BB. Zone 10: Intrazone policy is BQ and interzone policy is BQ. Zone 100: Intrazone policy Is BQ, interzone policy is BQ.
For calls between zone 1 and zone 10, the Best Bandwidth policy is selected. For calls between zone 10 and zone 100, the Best Quality policy is selected.
IP Peer codec selectionThe IP Peer codec selection consists of the Best Bandwidth and Master/Slave approaches, where the codec selection occurs separately on both sides based on local and received codec lists. For more information about codec selection, see IP Peer Networking Installation and Commissioning (NN43001-313).
The SIP Line side of a call is considered the local side to the Call Server (despite that a SIPL VTRK trunk is involved). Therefore, a SIP Line-to-SIP Line call is also considered as a local call. For SIP Line terminating calls, the codec list is sorted based on the policies of the originating zone and the SIPL zone (which is from the SIPL UEXT block) and is sent to the SIP IP Phone.

Bandwidth management

Local calls to a UNIStim IP Phone/TDM deviceThe codec list of SIP Line IP Phone and codec list of IP Phone and Voice Gateway (VGW) channel are used to find matching codecs. The codec is selected based on the zone policies. Local calls to other SIP Line IP PhonesThe codec list of SIP Line IP Phone is used for initial codec selection (because the codec list of the terminating side is not known). The initial codec is selected based on policies of both zones but only from the originator codec list. This type of call falls under the responsibility of the Session Description Protocol Transparency (SDP-T) feature. IP Peer (H.323 and SIP) calls over VTRKThe codec list of the SIP Line IP Phone is sorted based on SIP Line IP Phone interzone policy because the VTRK interzone policy must be Best Quality (BQ).
Limitations
The following codec selection limitations exist:
Session Description Protocol Transparency (SDP-T) limitation (video media stream)The codec negotiation for calls that fall under the responsibility of the SDP-T feature can be inaccurate (such as tandem SIP calls including SIP Line to and from SIP Virtual Trunk, and SIP Line to SIP Line). The Call Server deals only with supported codecs, while the SDP body for such calls is tunneled through the Call Server. The endpoints can choose a dynamic codec which is filtered out on the SLG/SSG. In this case, the bandwidth management procedures calculate bandwidth usage based on the remainder of the entire list. Also the media information for a particular session (call) is not displayed for tandem calls. This is also true for a SIPL user to SIPL user local call. SIP codec preference limitationA SIP endpoint cannot be told the order of preference in codec list during negotiation. In general, the order in the codec list received in the initial INVITE message does not guarantee the order in preferences during codec negotiation.
CS 1000 bandwidth management for SIP Line attempts to use all efforts sorting the codecs based on the zone policies and selecting the codec locally. However, due to these two previous limitations, the SIP IP Phone selects the real codecs. You must configure the SIP Line IP Phones with codec lists and codec preferences synchronized as closely as possible with the CS 1000 zone policy configuration. For more information see, Codec selection and negotiation (page 27).

Enable the CFAC feature on DN 3001. The CFWA FFC is defined as 5607 and CFWD FFC is defined as 5608. Step 1 2 3 Action Dial CFWA FFC + DN, for example, 56073001. Listen for a confirmation tone (or dial tone, if no tone resource is available) to indicate that CFAC to the DN is enabled. If you hear the busy or overflow tone then CFAC failed. Refer to the SIP response sent to the IP Phone for the failure:
404 Not foundMay due to FFC not defined. 603 DeclinedMay due to access restriction.

Feature implementation
The SIP IP Phone can forward all calls to another DN. Refer to the user guide for the SIP IP Phone to enable or disable CFAC.
Feature operation
After IP Phone-local CFAC is enabled, the SIP IP Phone sends a 302 (Moved Temporarily) response to all incoming calls. The Call Server and SIP Line Gateway (SLG) treat this response similar to the CFAC feature on the server side and the following behavior is expected:
Because extra messages are exchanged between the IP Phone and SLG and Call Server, the called party phone does not ring immediately (compared to server-side CFAC operation). The IP Phone can configure CFAC to any DN without DN validation or proper access restriction validation. This is standard practice. As a result, the call is not guaranteed to be successful. If the call fails (due to invalid DN or restricted access), the caller receives a ring back tone until the Call Forward No Answer (CFNA) feature is activated.
Note: To avoid user confusion, Nortel does not recommend IP Phone-local CFAC. IP Phone behavior variant
All supported SIP IP Phones share the same operation.
Feature implementation
You can configure some phones to Call Forward to a DN if the IP Phone is busy. However, because all incoming calls go through the Call Server and the phone status is synchronized between the Call Server and the IP Phone, then IP Phone-local call forward busy is not triggered.

Call Park/Retrieve
Call Park (CPRK) places a call in a parked state, similar to hold, where it can be retrieved by an attendant console or telephone.
Feature implementation
There is no change for SIPL UEXT on the Call Park/Retrieve feature. For more information about this feature, see Features and Services Fundamentals (NN43001-106).
Retrieve a parked call: Step 1 Action Dial SPRE + 72 followed by park to DN.
--End--
Zone Based Dialing support for Call Park and Call Retrieve
The Flexible Feature Code (FFC) must be used for Call Park/Retrieve to support Zone Based Dialing (ZBD) which always adds the zone prefix to a dial digit. To avoid the modification of the digit dialed, the FFC can be configured with a asterisk (*) at the beginning. The operation to park/retrieve a call is still the same except that FFC is used instead of SPRE. Park a call.

5. Select 3 (to start a 3-way call [local conference]). IP Phone behavior variant
Local Conference support is enabled on all IP Phone types. Some IP Phones support both the Server Conference and Local Conference features. After Local Conference is enabled, all conference calls use the local conference resource on the phone. For server conference support of individual IP Phone types, see Table 5 "SIP IP Phone capabilities" (page 33).
Call Waiting
Call Waiting notifies an active telephone that a second call is waiting to be answered on that Directory Number (DN).
Feature implementation
To enable the Call Waiting feature, you must configure Call Waiting Allowed (CWA) Class of Service (CLS) and Call Waiting (CWT) key on UEXT. Otherwise, the busy treatment is given.
Feature operation
If a user is active on a call, a new incoming call creates a new INVITE to the IP Phone. The IP Phone can accept the new call by placing the current call on Hold and answering the second call. The user can switch between two calls by pressing the DN key.
Note: Instead of using Call Waiting, a two-line call can occur by configuring two DN keys of the same number on one UEXT to receive the second call.

Speed Dial
69
Feature operation
SIP Line in a MADN group has the same feature operation as for other phone types, except for the following:
SIPL UEXT follows the same Multiple Appearance Directory Number Redirection Prime (MARP) rule as other phone types. Two SIPL UEXT can share the same DN; however, the user IDs must be different.
Speed Dial
If a user wants to initiate outgoing dialing, and the system expects a phone number, the user can enter a special prefix to indicate the use of short dialing features, followed by one to three digits indicating which number to use.
Feature implementation
The Speed Dial feature provisioning for SIP Line is the same as for other telephone types, with one additional step to configure the Speed Call User (SPCU) FFC in LD 57.
Note: Only one Speed Call User (SCU) key is supported. If you configure more than one SCU key, the lowest configured key is used.
Only the Speed Call user is supported for the SIP IP Phone. Use Speed Call to place calls by dialing a one-, two-, or three-digit code. You can use Speed Call for internal and external calls. Speed Call Controller is an administrative feature that is not available for SIP Line users.
Feature operation

Display of Access Prex for CLID or CONN number for SIP Lines
The Display of Access Prefix for CLID or CONN number (DAPC) for SIP Lines feature displays the correct dialable telephone number of the caller or the final connected party number on the SIP IP Phone display unit. You can dial back the caller using the displayed number. Applications such as Incoming call logs and the Directory of dialed or called numbers use the displayed number.
Feature implementation
The DAPC feature implementation for SIP Phones involves two major areas:
When there is an incoming call to the SIP IP Phone, this feature prepends the DAPC prefix code to the CLID of the caller and displays the correct dialable telephone numbers on the SIP phone display unit. When there is an outgoing call from the SIP IP Phone, in case of redirections of call, this feature prepends the DAPC prefix code to the CONNected party number on the SIP phone caller display unit.
Feature operation
Enable DAPC for SIP Lines feature.

The Communication Server 1000E Planning and Engineering (NN43041-220) and Co-resident Call Server and Signaling Server Fundamentals (NN43001-509) describe the maximum number of SIP Line users for each SIP Line Gateway and the maximum number of SIP Line users for each system. For TN space planning, each SIPL UEXT requires one SIP Line Virtual Trunk (VTRK) on each call for the duration of the call. SIP Line VTRK is not calculated against Incremental Software Management (ISM) licenses. There must be a 1:1 ratio between SIPL UEXT and SIPL VTRK TN. Configure all SIP Line users as the SIPL UEXT type and they operate the same as other line types, with the exception that you must assign one additional SIP Access Point for each user. Otherwise, in terms of TN planning and traffic planning, the same line and trunk calculations apply to the SIP Line feature.

Operating parameters
77
For each SIP Line user, two TNs are involved from Call Server perspective. For the SIP Line user to work properly, two TNs are involved: one for the SIP Line and the other for the SIP Line virtual trunk.
Operating parameters
The SIP Line feature has the following operating parameters:
The SIP Line Service (in CS 1000 Release 7.0) can co-reside with other applications. The SIP Line Gateway and SIP Line Service are bundled with the Signaling Server application, which is deployed using Deployment Manager. You must upgrade the Signaling Server software to enable and configure the SIP Line Service. Only one IP Phone for each user ID can be registered at a time. A second registration attempt (while first IP Phone is still registered) is rejected. The Make Set Busy (MSB) lamp status update depends on the supported the phone types. The Ring Again On Busy and Ring Again No Answer (RANA) feature notifications depend on whether the phone has a missed call log. The Flexible Feature Codes (FFC)-enabled feature suite only applies to the features listed in Table 5 "SIP IP Phone capabilities" (page 33). SIP Line cannot be a Converged Desktop user. SIP Line cannot be in the same MADN group as converged desktop (since SIP Line cannot be converged desktop user and converged desktop requires all TNs in the same MADN group has the same CLS). SIP Line supports Multiple Appearance Directory Number (MADN). However, for SIP Line users, MADN is supported only when using two SIPL UEXT with two different user IDs. Also, MADN is supported on the single IP Phone with two lines but only with the same DN. SCA Mode: In a single call arrangement (SCA) mode, MADN ensures only a single call is active on the DN, regardless of the number of DN appearances. A call on a DN appearance makes all other appearances busy. Thus, activity of one DN appearance is reflected on other appearances. This is known as cross-lamping.
DN, no other telephone on which the DN appears can bridge-into the call unless the call is placed on hold, except in the following cases:
MCA Mode: In a multi call arrangement (MCA) mode, MADN allows as many calls to be in progress as there are appearances of the DN. A call on a DN appearance does not make other appearances busy. Thus, activity of one DN appearance is not reflected on other appearances. Note 1: Configure the key as MCR or MCN. Note 2: In this mode, a call on a DN appearance cannot be bridged-into or picked-up by another appearance. Activity of one DN appearance is not reflected on other appearances. Multiple Line Appearance supports multiple Directory Numbers (DN) to the same device. Each DN can be shared with other devices or TNs in SCA or MCA MADN mode. The SIP Line feature cannot be on an Automatic Call Distribution (ACD) agent phone. This release does not support the following features:
Name dial Proactive Voice Quality Management (PVQM) Media security: The SIP Line IP Phones and trunks do not support
media security. The Class of Service (CLS) must be set to Media Security Never (MSNV) for SIP Line UEXT and SIP Line trunks. (This ensures that SIP media security negotiation issues do not occur.)
HELD SDP sent by the Nortel IP Phone 1120E or 1140E is not RFC2543 and RFC3264 compliant. As a result, SIP endpoints which strictly follow RFC 3264 can have issues when the phone holds the call.

On the SIP Line Configuration Details page, verify that the SIP Line Gateway Application check box is selected (default). This check box enables the gateway service on this node. Under the General section, in the SIP Domain name field, enter the name of the SIP domain. Note: If the domain name is configured in LD 15, ensure the same domain name is entered for the SIP Domain name. The SIP IP Phones use the domain name configured in LD 15 (instead of this field on the IP Node page), while registering with the SLG application. The domain name used in the IP Node section is in consideration of the future migration of supporting multiple domains and customers for each Signaling Server. The SLG requires IP Phone registration to include the domain name because the SIP standard verifies and challenges the login.

In the SLG Group ID field, enter the node ID. The SLG Group ID field is optional and is used in GR/BO configuration. It identifies whether a particular SIP Line user at the Branch Office belongs to a group when it registers at the Main Office. In the SLG Local Sip Port field, verify the local SIP port number of the SIP Line Gateway. (If the port number is different from the provided default value [5070], enter the new port number). The range is 1-65535. This field is mandatory for the SLG configuration. The SIP Line Gateways listens on the local SIP port. The SIP IP Phones use this port for registration purposes. In the SLG Local Tls Port field, verify the local TLS port number of the SIP Line Gateway (if the port number is different from the provided default value [5071], enter the new port number). The range is 1-65535. This field is mandatory for the SLG configuration. The SIP Line Gateways listens on the local TLS port. The SIP IP Phones use this port for registration purposes. Under the Virtual Trunk Network Health Monitor section, select the Monitor IP Addresses check box. (Optional) In the Monitor IP field, enter the IP address of the server to monitor, and click Add. (Optional) The IP address is added to the Monitored addresses list. The system will monitor activities on the specified server IP address. The monitored IP address serves the same purpose as for other virtual trunk-based applications. It is default to the TLAN gateway of a given Signaling Server, for checking the sanity of a TLAN network. If the monitored IP address does not respond, it is assumed that network connectivity is down. As a result, the application renders the VTRK service by disabling its own service. Addresses are removed by first selecting the IP address and then clicking Remove.

Under the SIP Line Gateway Settings section, from the Security Policy list, select the security policy for the SIP Line Gateway. The security policy settings are used for Transport Layer Security (TLS) support. TLS is used to secure signaling between SIP endpoints. The policy selected depends on the IP Phone capability to support TLS.
Security Disabled: Turns SIP TLS off. Best Effort: Turns SIP TLS on. The SIP Line Gateway will listen on its TLS, TCP, and UDP ports. Secure Local: Turns SIP TLS on. However, the SIP Line Gateway will listen only on its TLS port. (Uses TLS only if both ends support it.) Secure End to End: Nortel does not recommend enabling end-to-end security on the SIP Line Gateway, because all
Nortel Communication Server 1000 SIP Line Fundamentals NN43001-508 02.01 4 June 2010

IP Phones may not have the TLS capability. If you enable end-to-end security on the SLG, some IP Phones cannot be registered (when the IP Phones are using UDP or TCP transport). For more information about security, see Security Management Fundamentals (NN43001-604). 23 If security is enabled, configure the following:
From the Number of Bytes Re-negotiation list, select the number of bytes to be used for renegotiation. With this option, the session key used for the SIP TLS connection is renegotiated periodically. Renegotiation is triggered after the number of bytes specified have passed over the connection. To enable IP Phone authentication, select the Client Authentication check box. Enable this option if you want both sides to authenticate; when it is disabled, authentication is one-way. If you enable this option, sessions require greater overhead. To enable x509 certificate authentication, select the x509 Certificate Authentication Enabled check box. Enable this option to cause SIP TLS to provide both encryption and identity verification. Disable this option to allow the system, when operating on the IP Phone side of the SIP/TLS connection, to accept self-signed certificates from the server side. If you disable x509 Certificate Authentication, the system provides encryption only (it does not verify identity). If you select X509 Certificate Authentication, you cannot use self-signed certificates with SIP TLS.

This password is used by the SIP IP Phone when it connects to the SIP Line Server. In the Features section, select any other desired features for the SIP IP Phone. In the Keys section, you must configure the following keys.
16 17
Configure key 0 as the DN key (for example, SCR) Configure any key > 0 as the HOT U key
ATTENTION
A HOT U key label is available when UXTY is SIPL. The HOT U key is also known as the User Agent Directory Number (UADN) key. The UADN key is used to make and receive calls between the SIP Line Gateway and the Universal Extensions. However, this key is used only by the SIP Line Gateway (SLG) application. (The UADN is not dialed by end users. It is only used internally between the Call Server and the SIP Line Gateway application.) The configuration is Key <num> HOT U <DN> where the <num> parameter can be any key except 0. The User Agent Prefix (UAPR) prompt can be provisioned in the Customer Data Block (CDB - LD 15). See Table 12 "LD 15 Configure SLS_DATA" (page 117) and Procedure 2 Enabling the SIP Line Service and configuring the root domain (page 84). If the User Agent Prefix (UAPR) prompt is provisioned in the CDB, while you are configuring the new SIPL TN in Element Manager (after the PDN [Key 0 Primary DN] is configured), then the system generates a UADN (combining the Prefix and PDN). The HOT U DN is autogenerated (that is, it is created and stored in the database). However, it is not automatically displayed during configuration. The combination of UAPR+HOT U DN is only displayed when you print the TN. Element Manager does not automatically prepopulate your HOT U key with the UAPR. While configuring HOT U KEY, you can do any of the following: Manually configure the same DN as the UADN (if UAPR was configured). Configure a different DN as the UADN. Press Enter. The system automatically fills the UADN with a generated entry. The system generates an error if the UAPR is not found or if the UAPR is available but a valid UADN cannot be made.
Nortel Communication Server 1000 SIP Line Fundamentals NN43001-508 02.01 4 June 2010
Copyright 2009-2010 Nortel Networks. All Rights Reserved.
(If UAPR is not provisioned in the customer data block (CDB) , then you cannot press Enter for a HOT U key without configuring UADN.) If the total length of UAPR and PDN are longer than 7 digits, the UADN is not automatically created. You must manually configure the UADN in this case. You cannot configure the PDN and UADN as the same number. The UADN cannot be used as a redirection DN (for example, FDN, HUNT, or CFW to DN). The <DN> must fit into the customer dialing plan no matter if the <DN> is manually entered or if it is automatically entered by the software (if UAPR is configured in LD 15). After the DN is created by the software, the <DN> = <UAPR> + <Primary DN of universal extension>. UADN must be unique. That is, it cannot be the same number as another PDN or UADN for the same customer.

Subscriber Manager
Configure SIP Line users in Subscriber Manager. When adding a SIP Line IP Phone for a subscriber in Subscriber Manager, the SIP user name of the SIP Line IP Phone is updated from the user name, last name, first name, or preferred name of subscriber using the following four rules:
1. The SIP user name will be the Subscriber user name (if it is available). 2. If the subscriber does not have a user name and if the subscriber has
preferred name, then the a preferred name will be set as the SIP user name.
3. If the subscriber does not have a user name or a preferred name and
if the subscriber has a first name and a last name, then the subscriber first name will be set as the SIP user name.

Maintenance Table 17 Call impact Call type Simple, active calls Description A simple, active call is a call that is answered and involves only two parties. Simple, active calls are maintained for the duration of the call if the system is powered up or down.
Transient calls Other calls
If the call is an IP-to-IP call, the speech path is maintained for the duration of the call. If the call is a SIP-to-TDM call, the speech path is maintained as long as the DSP is available.
Transient calls are unanswered calls. Transient calls are dropped when the server reboots. All other calls are dropped. The user does not receive a BYE message to clear the signaling path. The BYE message relies on both parties hanging up the call to clear signaling.

LD 32 prints the SIP Line TN information. Only the registered TNs are displayed as part of the IDU command. The output information is printed only for the registered IP Phones and not for all IP Phones configured in LD 11 for that TN. When the IDU command is executed on any SIPL UEXT TN, the output prints all IP Phones (from 1 to 4) registered to the TN. Example: TN 62 13 is configured as UEXT TN and 4 IP Phones (1 SIPN, 1 FMCL and 1 SIP3) are registered to the TN.

LD 80
LD 80 has been changed to modify the set type as UEXT/SIPL in the output. In Release 7.0, the output format of LD 80 is changed to display the far end media endpoint IP which is the VTRK endpoint and the Media Endpoint IP for the Gateway Controller side. Earlier, only the IPv4 end-point IP was supported. The following example shows the IPv4 TRAC command (and response) when the command is issued on an idle TN: TRAC 0 5000 (Customer, DN) IDLE VTN 061 0 00 20 The following example shows the IPv4 TRAC command (and response) when the command is issued on a busy TN: TRAC 104 0 2 0 VTN 104 0 02 00 KEY 0 MCR MARP ACTIVE VTN 104 0 02 00 ORIG VTN 104 0 02 00 KEY 0 MCR MARP CUST 4 DN 3420 TYPE SLUEXT TERM VTN 104 0 01 00 KEY 0 SCR MARP CUST 4 DN 3410 TYPE 2004P1 MEDIA ENDPOINT IP: 47.11.215.69 PORT: 5200 MEDIA PROFILE: CODEC G.711 MU-LAW PAYLOAD 20 ms VAD OFF DIAL DN 3410 MAIN_PM ESTD TALKSLOT ORIG 22 TERM 22 EES_DATA: NONE QUEU NONE CALL ID 0 19968

LD 81
LD 81 prints the List (LST) or Count (CNT) of the TNs based on the provided feature (FEAT) input. LD 81 accepts the SIPL input parameter for the FEAT prompt. The output format of the overlay printing is not changed for SIP Line. The behavior of the UEXT TNs (non-SIPL) is not changed. For a SIPL TN, the TYPE of the phone is printed as SIPL. For CNT output, a new SIPL header is created to print the number of configured SIP Line IP Phones.

126
LD 83
LD 83 prints the List (LST) of TNs and the TN blocks (TNB). LD 83 includes the SIP Line output for the LST and TNB commands. The overlay output format is not changed. Since the LST command lists all the TNs configured in the system, and since there is no generic feature by which the output is sorted (like FEAT prompt in LD 81), the printed TYPE field is modified such that the following occurs:
For an Universal Extension TN, the configured UXTY type is printed. For a SIP Line Universal Extension TN:
The SCTL type configured for the TN (prefixed by SL) is printed. If multiple IP Phones are configured for the same TN, then all the
SCTL names configured are printed for the TYPE field. The SCTL names are separated by a forward slash (/). LD 83 also includes the SIPL prompts in the TNB output.
LD 117
LD 117 includes SIPL TNs for the following:
Inventory SETS Inventory LOCRPT STAT SERV STIP commands LOCRPT commands
LD 117 commands retrieve IP Phone information from the RLM table and since only registered IP Phones have an entry in the RLM table, non-SIPL Universal Extensions do not exist in the RLM table. Only the registered IP Phones are displayed in the output, and not all SCTL IP Phones configured in LD 11. The number of rows output equals the number of IP Phones configured for the TN in LD 11; however, only the data for register IP Phones is printed in the output. As a result, in the command outputs that follow, there is no differentiation between the TN type for SIPL and non-SIPL Universal Extensions.
Inventory SETS
The output for this command includes the SIPL TNs. The SIPL TNs are also included in the SETS Inventory report.

LD 117
127
The overall output format is not changed. The TYPE field is the SCTL type configured for the TN. If the SIP Line TN has multiple SCTL IP Phones configured, then the output has multiple rows (one for each of the IP Phone).
Inventory LOCRPT
The Inventory LOCRPT command generates an inventory with the location details for each TN. (This command is added from the ESA perspective.) The command includes the SIPL TNs information. The following example shows the output for a SIPL TN, 61 0, with 2 IP Phones (SIP3 and SIPN) registered to the TN: LD 117 INV GENERATE LOCRPT This command generates the inventory in the background and displays a message after the inventory is complete. INV PRT LOCRPT Locrpt inventory: 61 0 0 0,5000,CUST0DES1 , SIP3, REG, N/A, 47.11.84.158:5000 / <Unavailable>, ,,,"",, 61 0 0 0,5000,DES1CUST0 , SIPN, REG, N/A, 47.11.84.159:5000 / <Unavailable>, ,,,"",, The Inventory LOCRPT command is modified for SIP Line as follows:
The command prints multiple entries for a SIPL TN. The number of entries is the based on the number of SCTL IP Phones registered to the TN. However, only the registered IP Phones data is shown in the command printout. For different IP Phones, the following fields vary: SCTL Type, Client Hardware ID (TSN), Client IP address. The registration status is the registration status of the TN and not the individual IP Phone registration status. (There is no special field declared for the IP Phone registration status in the sipClientData structure because only the REG TNs are present in the RLM table.)

128
The remaining fields such as the location data fields (erl, ecl, etcc) are the same for all IP Phones, since these fields are configured for each TN. The HWID is not applicable for a SIPL TN. As a result, the hardcoded string N/A is printed instead of printing the HWID.
STAT SERV
The STAT SERV command prints the APPS as SLG when connected to the SIP Line Gateway (SLG). The command output also includes the number of registered and busy SIP Line UEXT TNs and Virtual Trunks (VTRKs). The STAT SERV command can be printed based on the SLG application using the STAT SERV APP SLG command.
STIP commands
The STIP commands include the multiple SCTL IP Phones printed in the STIP output. Only registered IP Phones of the TN are printed in the output. The number of rows printed for each TN is equal to the number of SCTL IP Phones configured for the TN in LD 11. The following example shows the output of the STIP command for a TN, 61 0 with 2 SCTL registered IP Phones: LD 117 STIP TN 61 0 TN type HWID STATUS HOSTIP SIGNALING IP 61 0 0 0 SIPN MAC: REG 47.11.84.132 47.11.84.158:5000 N/A CODEC(BW): G711u noVAD(1904)*, G711a noVAD(1904) MODEL: <USER Agent String> WID: 0 FWVer: N/A PEC: NT2K00GI TN type HWID STATUS HOSTIP SIGNALING IP 61 0 0 0 SIP3 MAC: REG 47.11.84.132 47.11.84.159:5000 N/A CODEC(BW): G711u noVAD(1904)*, G711a noVAD(1904) MODEL: <USER Agent String> WID: 0 FWVer: N/A PEC: NT2K00GI

The command prints multiple entries for the SIPL TN. The output contains the same number of entries as the SCTL IP Phones configured for the TN. For each entry, the varying fields are: TYPE (SCTL type configured), HWID (TSN data), signaling IP address (IP Phone IP address), and the Model (User Agent string of the SIP IP Phone) The remaining fields in the STIP output are common for all entries. For SIPL TNs, the firmware version (FMVER) field is printed as N/A because firmware is not applicable for SIP Line IP Phones. The number of entries printed for the command includes the number of entries for each TN. Since the HWID is not applicable for a SIPL TN, the hardcoded string N/A is printed instead of printing the HWID. The following STIP commands can be queried:
Table 18 STIP commands Command STIP ACF Notes The STIP command provides the active call failover status for active calls. There is no change to this command for SIP Line. Firmware (FW) is not applicable for the SIP Line IP Phones. As a result, this command executes a search only for the non-SIPL TNs. There is no change to this command for SIP Line, since the host IP address is the same as the SIP Line Gateway (SLG) IP address and the IP address is common for all the entries. This command prints the STIP input for those TNs whose model names match the given input. Since the method used to declare model names for the non-SIPL TNs is different from the User Agent (UA) string of the SIPL TNs, this command also traverses only the non-SIPL TNs. This is a new command used to query the SIP Line UA string. There is no change to this command for SIP Line. The term IP for each SIP IP Phone is different. As a result, the search criteria is modified to search all SIPL IP Phones to find the match. If a IP Phones term IP matches the input term IP, then the STIP data for that particular IP Phone is printed on the TTY.

Table 18 STIP commands (contd.) Command STIP TN STIP TYPE Notes There is no change to this command for SIP Line. The search criteria is modified to search all SCTL IP Phones to check if any type name matches the input type. If a match is found, then only the STIP report for that particular entry is printed on the TTY. There is no change to this command for SIP Line. Displays the Resource Locator Module information for the specified UNIStim encryption and Datagram Transport Layer Security (DTLS) capability.
LOCRPT commands
The Location Report (LOCRPT) commands print the SCTL SIP Line IP Phone information in the output. Only information for the registered IP Phones is printed. The number of rows printed is equal to the number of IP Phones configured for the TN in LD 11. The following example shows the output for a SIPL TN with 2 registered IP Phones registered: LD 117 => LOCRPT ALL

131
The LOCRPT commands includes all the SCTL IP Phones in the locrpt output. For a SIPL TN, the output has the same number of entries as the number of SCTL IP Phones configured for the TN. For each entry, the varying fields are: TYPE (which is the SCTL type), HWID (TSN data), and signaling IP address (IP Phone IP address) The remaining data is common for all the IP Phones. The number of entries counter is incremented for the number of TNs and this also includes the multiple entries for each SIPL TN. The registration (REG) status printed in the output is the registration status of the TN and not the registration status of each IP Phone. Since the HWID is not applicable for a SIPL TN, the hardcoded string N/A is printed instead of printing the HWID. The following LOCRPT commands can be queried based on different search criteria:
Table 19 LOCRPT command Command LOCRPT ALL Notes Prints a location report for all registered TN entries in the RLM. By default, this command prints the multiple entries for SIP Line in accordance to the number of SCTL IP Phones configured. DN is common for the TN and is not specific for each IP Phone. ECL is common for the TN and is not specific for each IP Phone. ERL is common for the TN and is not specific for each IP Phone. Since there is no HWID for the SIP IP Phones, the LOCRPT HWID command search is performed only for the non-SIPL TNs to determine if the input HWID matches with the IP Phone HWID.

Table 19 LOCRPT command (contd.) Command LOCRPT IP Notes If the signaling IP address for any TNs match the input IP address, then the LOCRPT of that TN is printed. The searching function is modified to include the multiple IP Phones for the SIP Line TNs. These location data fields are common for each TN and are not different for each SIP Line IP Phone. There is no change to these commands for SIP Line.
LD 20
LD 20 includes the SIP Line prompts (SIPL, MCCL, SIPN, SIP3, FMCL, TLSV, SIPU, NDID, SUPR, and HOT U). The overlay also includes the TNB output. LD 20 is also accepts SIPL as a type. TYPE=SIPL is useful if you want to print any TN based on any SIPU value. A new SIPU prompt is prompted on the TTY, if TYPE=SIPL. If any TNB SIPU matches the input, then that particular TNB is printed. An SCH error is printed if an invalid SIPU is entered. If TYPE=SIPL is entered, then you must not enter any input for the fields such as TN and CUST, since these fields validate the input with the actual TN type (which is UEXT but not SIPL). As a result, the output does not print the required TN value. For TYPE=SIPL, you must ensure that the only prompt that can be configured is SIPU (input to SIPU is optional). LD 20 includes a new SUBR field that indicates the features that the SIP Line IP Phone has subscribed for when it registers (this is done by default for all SIPL UEXT, regardless of IP Phone type). If a SIPL IP Phone is registered, in LD 20, the prt TNB gives the output of SUBR. The included features are Message Waiting Indication (MWI), Ring Again (RGA), Call

Waiting (CWI), and Make Set Busy (MSB). The SIP Line Gateway receives a notification message (AML SFN msg) from the Call Server when these features start for a SIPL UEXT.
LD 21
LD 21 accepts SLS (SIP Line Service) as a response for the TYPE prompt. LD 21 also prints the new prompts introduced in LD 15: SLS, SIPL_ON, SIPD, NMME, and UAPR. These prompts (and their values) are printed when the response to TYPE is CDB or SLS. LD 21 prints the new SIPL response introduced for the PCID prompt.
