Description:This is a copy of Issue 0009686, which I uncorrectly assigned to chan_agent

I have downloaded (yesterday) the 1.2 branch from svn ...
When running: asterisk -vvvvc
loaded modules:
[modules]
autoload=no

load => pbx_functions.so
load => pbx_config.so
load => codec_a_mu.so
load => format_pcm_alaw.so
load => codec_ulaw.so
load => codec_alaw.so
load => format_pcm.so
load => func_uri.so
      ;required by app_dial and chan_sip
load => res_features.so
load => app_dial.so

      ;playback and echo apps ...
load => app_playback.so
load => app_echo.so
load => codec_gsm.so
load => format_gsm.so
load => format_wav_gsm.so

load => chan_h323.so
load => chan_sip.so

load => chan_local.so


When I do: > stop now
asterisk hangs up, but locks:
*CLI> stop now
Beginning asterisk shutdown....
Executing last minute cleanups
Asterisk cleanly ending (0).



I attached gdb to the locked process:

Move to Asterisk 1.4 with heavily updated chan_h323, and everything should be much better. There are huge changes from 1.2, so we cannot backport them from 1.4.
By: Cesc Santasusana (cescsanta) 2007-05-09 14:40:29

Well, for many reasons I am not allowed to jump to 1.4.
And as previous versions of 1.2 seem to work fine when hanging up, the bug could be traced and solved. 1.2 is still being released ... or am I wrong?
Anyway, you guys decide ...

By the way, I am not trying to port anything from 1.4 to 1.2 .. somethings have been improved in the latest version of 1.2 and I want to use them, but a bug has been introduced. If you wannt leave it there ... fine.

1.2 is now in a security fixes only state, thus this bug will not be fixed there.
