I was using asterisk-18.104.22.168-rc5 until this morning, just downloaded and installed asterisk-22.214.171.124. The rest of this post is wrt rc5. I won’t know if the behavior is in the release version until later today or tomorrow.
At the moment I have two Asterisk servers. One is being used as a switchboard for some IP phones. It’s a dev PBX for connecting developers/testers to the actual application. The other server is the actual application, with most of the work being done via an AGI daemon.
The SIP phones I’ve been given are Cisco 7905g desk sets. These are kind of old now, but that’s what I have.
Running on Debian 4.0.
Things work pretty well when I bring up both servers. I can call from the IP phones to the dev PBX and have it redirected to the core server where stuff happens and results percolate back to the phone (I hear recordings on the handset). This goes on for some period of time.
If, however, I leave the systems alone for a while (e.g. long lunch or overnight) the phones will no longer connect to the dev pbx. I tried rebooting the phones but no dice. I ran tcpdump on the dev pbx server and it clearly shows SIP packets coming in from the phones but there is no response from Asterisk to the phones. I do see some traffic between the two peers.
I’ve been running with verbose set to 3 and now I’ve added debug of 3, but thus far I’ve seen no messages indicating a problem.
I’ve gone through the console commands and showed everything that made any kind of sense. Nothing jumped out at me.
Is there something else I can do to trace this down? Assuming, of course, that the problem continues to occur in 126.96.36.199.
