We have added some SIP trunks to a 3300 V8, inbound calls are coming in fine but outbound calls drop after about 150 seconds.
The 3300 sits on the local network behind a firewall, we have a dedicated SIP trunk gateway with a static IP of 84.252.199.200 (changed for security) on the public side of the firewall which is tunneled though to the local IP of the 3300 (192.168.1.11).
The TalkTalk SIP circuit is pointed at the endpoint which is the gateway public IP.
I'm guessing that TalkTalk are rejecting the calls as they are tagged with the local IP of the 3300 rather than the gateway IP but I can't see how to resolve this?
Or am I barking up the wrong tree.
