Has anyone been successful in getting the AT&T SIP trunks working on the SV9100 ?
I followed the NEC configuration guide for them but I can't get outbound calls to work, incoming is ok.

Check your firewall. Wireshark off processor will tell you volumes where this is failing.

Check if SIP ALG is turned on in your router. It will play hell with SIP trunks. If your trunks only work one way, your trunks are not registered.

Problem solved, AT&T had to NAT the NEC 84-26 IP address in their session border controller.
