The SIP FXO/Line port page configures SIP gateway FXO/Line ports to support voice calls from IP networks to the PSTN. Once FXO ports are configured and Survivability is enabled, FXO ports can act as a LAN side gateway if the softswitch becomes unreachable.
This section includes the following topics:
- SIP Gateway Overview
- Using the SIP GW Page
- Configure Global SIP Gateway FXO/Line Port Settings
- Register with the SIP Server
- Configure SIP Gateway FXO Ports
