[Freeswitch-users] mod_sofia not binding to port 5060

Good afternoon. We've got a freeswitch machine, no external SIP gateways for outside calls, eight extensions, two conferences, and a completely public IP for the machine in question (no NAT weirdness), running on Debian 6 (weezy/sid). I woke up this morning, to find that sip_external_port 5060 was not listening, though it was enabled in config/vars.xml. The internal port, 5080, is listening, and I have folks confirming that they can speak using that port. I've set netcat to listen via 5080, so I know it isn't firewalled, or not at least ina conventional manner. Any help you all can provide, things I can check, would be greatly appreciated. Sincerely, Brandon McGinty-Carroll
