    Having issues getting a customer setup with AT&T SBC onsite. PBX to Switch, Switch to SIP port on SBC. Gave AT&T a private IP to configure on their LAN interface of the SBC. Create SIP provider for AT&T and use the private IP for the sip server. Will this work? At one point we had inbound calls working but not outbound. Got to be something i'm missing.

    I am not sure if this will work as this also depends on the Provider, but I would imagine that you must also populate the "Outbound Proxy" field in the Provider Settings to be the LAN IP of the SBC.

    Were you ever able to get this resolved? We seem to have a similar setup and issue with a Bright House trunk.
