I am trying to track down a problem which is occurring on about 1% of the phone calls through a customer's system. Layout looks like this: PSTN <-- PRI <-- Asterisk A <-- IAX Trunk over point to point T1 <-- Asterisk B <-- SIP over LAN <-- Polycom IP501 1) The user on the Polycom IP501 phone dials a number. 2) It is routed across the LAN to an Asterisk PBX 3) The call is then routed across the T1 via IAX to another Asterisk Server 4) This server drops the call on a PRI line 5) The callee will hear their phone ring 6) On the Polycom you hear 5-10 seconds of silence then a fast busy. 7) The callee answers but no one is there. I see the following in my debug log (on Asterisk B) but I'm not sure if any of these messages are abnormal: Aug 21 08:39:18 DEBUG[16560] channel.c: Didn't get a frame from channel: SIP/101-40c4 Aug 21 08:39:18 DEBUG[16560] channel.c: Bridge stops bridging channels SIP/101-40c4 and IAX2/ROUTING-6 Aug 21 08:39:18 DEBUG[16560] chan_iax2.c: We're hanging up IAX2/ROUTING-6 now...

Aug 21 08:39:18 DEBUG[16560] chan_sip.c: update_call_counter(101) - decrement call limit counter Anyone have any ideas on this? -Jonathan Jonathan Creasy Network Engineer BluegrassNet Development www.bgnd.com www.bluegrass.net o. 502-589-4638 c. 502-889-5567 h. 812-206-1830 -------------- next part -------------- An HTML attachment was scrubbed...
