Voip Configuration Examples: Fxs-To-Fxs Connection Using RSVP
This section uses four different scenarios to demonstrate how to configure Voice
over IP (VoIP). The actual VoIP configuration procedure depends on the topology
of your voice network. The following configuration examples should give you a
starting point, but you will need to customize them to reflect your network
topology.
Configuration procedures are supplied for the following scenarios:
• FXS-to-FXS Connection Using RSVP, page C-1
• Linking PBX Users with E&M Trunk Lines, page C-7
• FXO Gateway to PSTN, page C-10
• FXO Gateway to PSTN (PLAR Mode), page C-12

Note PBXs should be configured to pass all dual tone multifrequency (DTMF) signals
to the router. Cisco recommends that you do not configure, store, or forward tone.
Note If you change the gain or the telephony port, make sure that the telephony port
still accepts DTMF signals.
