Description: | even if I using same codec (disallow=all, allow=g729) on both channels, I never see 'Packet2Packet bridging...' message, like in sip-sip, sip-skinny, skinny-skinny bridging. I think, that h323 is using same RTP subsystem, so Packet2Packet bridging should be possible to avoid RTP go through asterisk core, like in other cases. also some unnecessary warnings about codecs are displayed when calling h323->sip, reverse direction sip->h323 is without warnings. since both my ends supports g729, I have no g729 installed and expecting, that asterisk will do simple passthrough. In general it works, but imho, it should work better, with Packet2Packet bridging and avoid warnings below. ****** ADDITIONAL INFORMATION ****** -- SIP/xxx-gw-0822d978 is ringing [Feb 1 15:50:08] WARNING[19297]: channel.c:2968 set_format: Unable to find a codec translation path from g729 to slin [Feb 1 15:50:08] WARNING[19297]: indications.c:122 playtones_alloc: Unable to set 'H323/ip$192.168.40.7:51656/237' to signed linear format (write) -- SIP/xxx-gw-0822d978 is making progress passing it to H323/ip$192.168.40.7:51656/237 | ||

In 1.4, if the absolute timeout were reached on a call, no matter what the return value of ast_spawn_extension was, the pbx would attempt to go to the 'T' extension or hangup otherwise. The rearrangement of this function in trunk made this check only happen in the case that ast_spawn_extension returned 0. If ast_spawn_extension returned 1, then the fact that the timeout expired resulted in a no-op, and would cause an infinite loop to occur in __ast_pbx_run. This change fixes this problem. Now timeouts will behave as they did in 1.4 (closes issue ASTERISK-11038) Reported by: pj Tested by: putnopvut ........ r113838 | qwell | 2008-04-09 12:56:07 -0500 (Wed, 09 Apr 2008) | 2 lines Fix a small file handle "leak" pointed out by jjshoe on #asterisk. ........ r113840 | file | 2008-04-09 13:05:40 -0500 (Wed, 09 Apr 2008) | 4 lines Enable enough RTP bridging to allow P2P to work.

Colp (jcolp) 2008-04-10 08:55:00 I can't reproduce this with ulaw on both sides, and don't have the stuff to try g729 on both sides. By: pj (pj) 2008-04-10 09:21:49 I will try to change to g711 and will report. By: pj (pj) 2008-04-10 10:29:12 I probably found source of issue, it's rtp packetization settings: when I set 'allow=g729:60' on SIP side, Packet2Packet bridging between SIP and H323 is working. When I leave simply 'allow=g729' on both SIP and H323 side p2p bridging is not working. Setting 'allow=g729:20' on H323 side (to be same as is by default for g729 on sip side) has no affect, because h323 end device still reports, that is receiving 60ms samples. Seems, that something is broken with rtp packetization settings on for h323 channel. By: Joshua C. Colp (jcolp) 2008-04-10 10:33:26 I do not believe chan_h323 has support for packetization settings... that would be a separate issue. So P2P does indeed work when the conditions are right and I can close this out? By: pj (pj) 2008-04-10 10:39:54 OK please close this ticket, I will open some new for this, because doc/rtp-packetization.txt says, that chan_h323 should support rtp packetization settings, (at least should leave default 20ms packetization, and not change to 60ms). thanks By: Joshua C. Colp (jcolp) 2008-04-10 10:52:12 Closed per reporter's statement that the issue is actually being caused by packetization issues. |
