Comments: | By: Olle Johansson (oej) 2004-12-23 01:11:07.000-0600 "unable to create channel" is usually a configuration error. Do you really have a confirmed bug? Also, according to the bug guidelines, when reporting SIP bugs you have to add output from "sip debug" in your asterisk server. In this case, also sip.conf and extensions.conf. There is no way I can see if there is a bug with the information provided. If you have questions about this, please find a bug marshal in the #asterisk-bugs channel on IRC. /Olle By: Olle Johansson (oej) 2004-12-23 01:11:47.000-0600 ...and - again - this is not qualified as a MAJOR bug... By: Clod Patry (junky) 2004-12-23 05:23:38.000-0600 If you can provide us any debug file that would help a lot. And also, if you can paste ur part of sip.conf and your Dial line in extensions.conf, that would be really cool. By: Mark Spencer (markster) 2004-12-23 05:59:01.000-0600 Since you are placing a SIP bug, you should include a SIP debug message. You already have -4 karma. If you continue to place bugs without reading the bug guidelines, they will simply be deleted in the future. By: heison (heison) 2004-12-23 06:51:27.000-0600 comparing the 2 CVS (CVS-HEAD-12/08/04-23:37:47 & CVS-HEAD-12/22/04-23:52:15), here is what I see: with cisco1 calling extension 1520 being an internal call, the later CVS doesn't seem to believe it is a call with no NAT and tried to transmit with NAT. Comparing sip.conf.sample of the 2 CVS, I can't find behaviour change: 124d123 < ;registertimeout=20 ; retry registration calls every 20 seconds (default) 147a147 > ; auth auth By: heison (heison) 2004-12-23 07:00:29.000-0600 The dial line in extension.conf: KITCHEN=Zap/4 exten => 1520,1,Macro(stdexten,1599,${KITCHEN}) By: heison (heison) 2004-12-23 07:02:18.000-0600 and the macro: [macro-stdexten] exten => s,1,Dial(${ARG2},20,Tr) exten => s,2,Voicemail(u${ARG1}) By: Olle Johansson (oej) 2004-12-23 07:20:05.000-0600 Neither debug file includes the text "Unable to create/find channel". And in your example you are dialing a ZAP channel. You need to follow up with debug files that include the problem you report.

We've sorted this out over the IRC. It wasn't a bug, but introduction of a change in the logic that may look like a bug since there was no change in the config files. I recommend no change of karma. Heison: Please remember to report properly in the future, with all facts like SIp debug, config files. We could have sorted this out more quickly with a proper report. Thank you and merry xmas! |
