Avoid !! not a SIP Gateway, I configured it to talk to freeswitch for incoming calls but outgoing via PSTN never worked, I contacted CAMRIVOX and they said “The Flexor ATA is an FXS adapter. It is a VoIP device designed to provide an FXS port to an analog telephone handset so that calls can be made over a SIP connection with legacy support to an analog trunk via an FXO port. It is not an FXO gateway which is the equipment required to support the scenario you have described.”
