Configuring VoIP trunks

You can add one or more VoIP service providers to the FortiVoice unit trunk configuration. The VoIP service providers deliver your telephone services to customers equipped with SIP-based PBX (IP-PBX).

If you are accessing a FortiVoice FVE-20E2, FVE-50E6, or FVE-50G2 model that is a survivability branch managed by a main office FortiVoice system, Trunk > VoIP > SIP can show two SIP trunks mapped to two analog extensions associated with the FXS ports. For more details about survivability branches, see the FortiVoice Local Survivable Gateway Deployment Guide.
