I have a sip trunk configured, outbound calls are ok but incoming calls don't work. When I issue the command âshow sip-ua connections udp detailedâ I get this
âRemote-Agent: IP ADDRESS, Connections-Count:1
Remote-Port Conn-Id Conn-State WriteQ-Size
=========== ======= =========== ===========
5060 1 Established 0â
however after a while when I issue the same command it shows âNo Active Connections Foundâ.
It seems that the SIP registration times out, but does an incoming call triggers the trunk to re-register? How can I make sure that the SIP registration doesn't timeout?
When the sip trunk is up and if I make an inbound call I get the attached output, which I take is that it rings the extension but after no answer it send it to voice mail on 4888.
Please find attached debug ccsip messages output.
