[Freeswitch-dev] Mod_dingaling 32 bits

21 Sep 2010

      Hi All,

I understand, mod_dingaling on 32-bit machine can works unstable,
but on the my machine this behaviour stable repeating.

My build from ~Sep, 15.

I think, need to continue debug mod_dingaling.

This is explanation of behaviour:

1. If I oroginate call through GV, and recepient pick up handset,
everything OK, conversation goes, etc.

2. But, problem in the following scenario:

  - I call from FS by GV to PSTN
  - PSTN phone start calling
  - I cancel call on orogonator's side
  * - rcpt phone continue calling!
  * - when I pick up handset on rcpt side, hear nothing.

Please, see log in there:

I noticed, when I cancel call on orogonator's side, mod_dingaling prints
correct log values, like:

2010-09-20 21:29:09.925255 [DEBUG] mod_dingaling.c:1342 dingaling/xmppc/+12404760839@voice.google.com CHANNEL KILL
2010-09-20 21:29:09.925255 [DEBUG] switch_core_session.c:1210 Session 13 (dingaling/xmppc/+12404760839@voice.google.com) Locked, Waiting on external entities
2010-09-20 21:29:09.925255 [NOTICE] switch_core_session.c:1228 Session 13 (dingaling/xmppc/+12404760839@voice.google.com) Ended

You see, session 13 Ended.

But, RCPT phone continue calling!

When I pick up RCPT-handset, I see log messages:

2010-09-20 21:29:16.442028 [DEBUG] mod_dingaling.c:1002 Send Candidate 173.79.240.220:24818 [zkNRjTp5rkWS9Kim]
2010-09-20 21:29:16.442028 [DEBUG] mod_dingaling.c:3067 Creating an identity for 0872291417 Google Voice<+12404760839>  12027139373
2010-09-20 21:29:16.442028 [NOTICE] switch_channel.c:779 New Channel dingaling/12027139373 [cca305a6-1fc5-df11-9af2-005004c3cb7e]

Looks like mod_dingaling continue work on canceled call, despite on "session 13 Ended".

And, at the end (after pick up handset on recepient side), I see:
2010-09-20 21:29:16.622104 [DEBUG] switch_core_session.c:1210 Session 14 (DingaLing/new) Locked, Waiting on external entities
2010-09-20 21:29:16.622104 [NOTICE] switch_core_session.c:1228 Session 14 (DingaLing/new) Ended
2010-09-20 21:29:16.622104 [NOTICE] switch_core_session.c:1230 Close Channel DingaLing/new [CS_DESTROY]

I assume, mod_dingaling generates 2 sessions per phone call, and destroy only one, when originator drops handset...

Interesting, is this behaviour repeatable on another OS/builds?
