[Asterisk-Users] Dropped calls -> reproducing scenario
So I think I am able to reproduce the dropped call scenario. Here is what I do to get a dropped call: 1. Call 1-800-tmobile 2. Go true their IVR and get connected to the customer service IVR 3. Enter my number and SSN 4. press 0 5. Then the audio please hold starts. After about 2-4 seconds the call gets dropped. (fast busy tone) The time on my phone will stop running (call time) and I will get this error in the asterisk logs: -- Executing Dial("SIP/113-94a1", "Zap/g1/18008662453") in new stack -- Called g1/18008662453 -- Zap/1-1 answered SIP/113-94a1 Apr 29 10:41:14 WARNING[-1210664016]: chan_sip.c:495 retrans_pkt: Maximum retries exceeded on call 113 for seqno 102 (Request) -- Hungup 'Zap/1-1' I did this 4 times and all the time the exact same scenario. When I called from my cellphone everything was fine. Any ideas? Thanks, Thomas

I'm not too expert but it looks like you have some network/nat problem from asterisk to your sip client, calls get terminated for a sip problem, not for a telco one.

Are you using busydetect and/or callprogress on your Zap channel? Their hold music might be setting this off. Cheers, Vic Cross
