Description:	The problem described in ID:0009335 has resurfaced in 1.4.19. While there were no problems on sat-links in 1.4.17 i get a hangup on calls originated from remote (sat) side. ****** ADDITIONAL INFORMATION ****** [May 15 16:28:17] VERBOSE[6420] logger.c:     -- Local/41414221424@from-sip-c528,1 stopped sounds [May 15 16:28:17] VERBOSE[6420] logger.c:     -- Local/41414221424@from-sip-c528,1 answered SIP/414101523-08830d70 [May 15 16:28:17] VERBOSE[6421] logger.c:   == Spawn extension (my-dialplan, 41414221424, 8) exited non-zero on 'Local/41414221424@from-sip-c528,2' [May 15 16:28:17] VERBOSE[6421] logger.c:     -- Executing [h@my-dialplan:1] GotoIf("Local/41414221424@from-sip-c528,2", "0?100:2") in new stack [May 15 16:28:17] VERBOSE[6421] logger.c:     -- Goto (my-dialplan,h,2) [May 15 16:28:17] VERBOSE[6421] logger.c:     -- Executing [h@my-dialplan:2] Set("Local/41414221424@from-sip-c528,2", "result=ANSWER") in new stack [May 15 16:28:17] VERBOSE[6421] logger.c:     -- Executing [h@my-dialplan:3] GotoIf("Local/41414221424@from-sip-c528,2", "0?4:6") in new stack [May 15 16:28:17] VERBOSE[6421] logger.c:     -- Goto (my-dialplan,h,6) [May 15 16:28:17] VERBOSE[6421] logger.c:     -- Executing [h@my-dialplan:6] GotoIf("Local/41414221424@from-sip-c528,2", "1?7:100") in new stack [May 15 16:28:17] VERBOSE[6421] logger.c:     -- Goto (my-dialplan,h,7) [May 15 16:28:17] VERBOSE[6421] logger.c:     -- Executing [h@my-dialplan:7] DeadAGI("Local/41414221424@from-sip-c528,2", "rm_missed_call.agi|0414101523") in [May 15 16:28:17] VERBOSE[6421] logger.c:     -- Launched AGI Script /var/lib/asterisk/agi-bin/rm_missed_call.agi [May 15 16:28:17] VERBOSE[6421] logger.c:     -- AGI Script rm_missed_call.agi completed, returning 0 [May 15 16:28:22] NOTICE[6396] chan_sip.c: Peer '414101523' is now Reachable.

Comments:	By: Chris Tooley (ctooley) 2008-07-01 10:15:56 Please post more of the CLI output, it appears that the peer may be losing connectivity.  Note that 1359ms is a very long latency to try to make the call work across, I realize that's a different phone, but more output would be helpful.  See the notes on 9335 for creating the output.  Please attach it as a file and not in a Note. By: Joshua C. Colp (jcolp) 2008-07-02 21:32:24 As mentioned please attach more information (like the SIP debug) By: Manuel Räber (fratzr) 2008-07-03 01:02:56 Sorry, but I can't help at this moment, as the remote satellite equipment is quite far away and temporarily not in use. I hope someone else can test that for us. By: Tilghman Lesher (tilghman) 2008-07-25 18:07:13 Suspended.  If someone can provide the requested information, then please reopen this issue.  If you need assistance, please contact a bug marshal in the #asterisk-bugs channel on the Freenode IRC network. By: Manuel Räber (fratzr) 2008-09-15 06:18:03 Finally I was able to test and log this again. In 1.4.21.1 we're still seeing the same problem. Calls originated from the remote site (satellite-side) drop after approx. 20 seconds. The call starts Sep 15 13:18:09 from 414101523 to 0041414221424: [Sep 15 13:18:09]     -- Executing [0041414221424@from-pfiga:13] Dial("SIP/414101523-09cd4ad8", "SIP/41414221424@sip.irtech.ch") in new stack The call drops at 13:18:27: [Sep 15 13:18:27]   == Spawn extension (from-pfiga, 0041414221424, 13) exited non-zero on 'SIP/414101523-09cd4ad8' By: Leif Madsen (lmadsen) 2008-12-09 08:09:16.000-0600 Requested information posted. Assigned to file. Does this help? By: Joshua C. Colp (jcolp) 2008-12-09 11:15:31.000-0600 I have confirmed that this has been fixed by revision 128912 in recent versions.
