I have an issue making 2 or more calls within a short space of time between two phones, one native IP behind a CME running 184.108.40.206 and the other behind a 2811 router with a basic H323 voice gateway configuration. The (edited) configs for each end are attached.
The first call from one phone to the other (or using csim) goes through fine.
However, once the call is ended, if a subsequent call is made within a minute or two afterwards to the same phone (or a phone via the same destination gateway), the call fails and I get the following debug output from h225/h245.
*Jul 16 09:01:49.052: h323chan_chn_process_read_socket: fd=2 of type CONNECTED has data
*Jul 16 09:01:49.052: h323chan_recvdata: recv failure on fd=2: errno=254 errstr=Connection reset by peerh323chan_chn_close: Calls Exist on socketfd=2 Owner
*Jul 16 09:01:49.052: h323chan_close: TCP connection from fd=2 closed
Anybody have any ideas? I've run out and as I write this am seconds away from banging my head against my desk.
By default on the gateway, it will use UDP for SIP.
I think your problem was TCP socket related, so using SIP because it is UDP would probably fix the problem. Technically, you're hiding it, but it's up to you whether or not you would like to track down the problem.
