the others are null.
test context config as fellowing:

Please provide the console log of a problem reproduced as per following:
1) Prepare test environment (reduce the amount of unrelated traffic on the server);
2) Make sure your logger.conf has the following line:
  console => notice,warning,error,debug
3) restart Asterisk with the following command:
  'asterisk -Tvvvvvdddddngc | tee /tmp/verbosedebug.txt'
4) Enable SIP transaction logging with the following CLI commands (1.4/trunk commands in parenthesis):
set debug 4 (core set debug 4)
set verbose 4 (core set verbose 4)
sip debug (sip set debug)
5) Reproduce the problem
6) Trim startup information and attach verbosedebug.txt to the issue.

Also, it would be helpful to see the same output with an IAX call (don't use 'sip set debug' command in that case).

attach the same output but for a working scenario (with IAX2 call).
By: shawn (welles) 2007-03-25 21:26:30

serge-v,please have a check the output of iax2 for the same scenario .thanks

ok, thanks.

Does this problem occur if a sip device calls into an extension that launches festival too?
By: shawn (welles) 2007-03-26 20:02:31

serge-v, i use sip phone to have a call which launches festival. i can hear nothing. BTW,the following is my sip.conf :
/********************************
[general]
port = 5060           ; Port to bind to (SIP is 5060)
bindaddr = 0.0.0.0    ; Address to bind to (all addresses on machine)
disallow=all
allow=alaw
context = from-sip-external ; Send unknown SIP callers to this context
callerid = Unknown
[1000]
type=friend
username=1000
nat=yes
host=dynamic
secret=1234
context=test
*******************************/

extensions.conf :
/*****************************
[test]
exten => 1000,1,answer
exten => 1000,n,BackGround(demo-congrats)
exten => 1000,n,festival(welcome)
exten => 1000,n,hangup
******************************/

i can hear 'demo-congrats' but not welcome ,while using iax2 device i can hear both.

it is a bug or i make something wrong?
By: Serge Vecher (serge-v) 2007-03-28 08:10:33

This indeed looks like a bug. From debug you can see that the SIP channel is promptly hung up after Festival gets involved. I'm going to downgrade the severity though, because you could replace Festival with a regular playback. Waiting for developer to pick this up.

welles: it is something that is remotely related to this bug, but a recently committed patch will hang up at the point where you see a "I should never be called!" warning. Can you please check out 1.4 from svn (rev > 59341) and test to see that Festival still works with and IAX channel?
By: Serge Vecher (serge-v) 2007-03-29 12:33:34

relating to 8590, even though the problem there seem to be the lack of Answer(), something that is present here, but perhaps the issue needs a second look.
By: shawn (welles) 2007-03-29 21:28:46

using asterisk 1.4.2:sip channel doesn't hangup when executing festival appliction. but i still can't hear voice. all festival applications can be executed. while iax2 channel works fine with festival.
using SVN-branch-1.4-r59363:the same with asterisk 1.4.2 when channel is sip.
console info as followings:
/**************************************************

when channel is iax2, it becomes much worse. when executing  festival application, channel hangup. console info :

russell, looks like the patch from 8286 has exacerbated the situation here. I didn't reopen the issue, since it seems that the Festival app seems to be the culprit here. In case you have a second to look this over, please do ;)
By: Joshua C. Colp (jcolp) 2007-10-22 12:20:47

I'm suspending this for now since it's a 1.2 issue. If it's applicable to 1.4 feel free to reopen and I will attempt to get Festival going and debug things.
