[Asterisk-Users] H.323 channel problems

[Jan Rychter]

I have hit a problem where chan_h323 sometimes doesn't hang up properly
and stays stuck in the "Up" state, with asterisk consuming 100% of CPU:

*CLI> show channels
        Channel  (Context    Extension    Pri )   State Appl.         Data

That's after hanging up (in gnomemeeting) on a H.323 call that is then
bridged to IAX2.

Now, before I go running to the bugtracker, I'd like to ask some general
questions.

The H.323 channel readme says:

  NOTICE: Whatever you do, DO NOT USE distrubution specific installs
  of Open H.323 and PWLib. In fact you should check to make sure
  your distro didn't install them for you without your knowledge.
  Check everything out of CVS. If you dont know how to deal with cvs, learn.
  Also, if you are not using the listed versions of Open H.323 or PWlib
  you are on your own, sorry.

And:

  Some chan_h323 users have reported success and others have reported dramatic
  failures when using newer versions of Open H.323. We haven't personally tested
  this and will not be able to assist you if you have 'issues'. Sorry.
  
  IN OTHER WORDS: Run Open H.323 v1.11.7 nothing newer nothing older if u want
  this to work.

How does this relate to my bug? I'm using openh323-1.12 and pwlib-1.5.0
that I compiled myself. Do they have problems? Does this mean I am on my
own?

Perhaps it's worth trying to report the bugs to distribution maintainers
if indeed the distribution-specific installs of openh323 are this buggy?

The requirement of using this particular version of openh323 is a
problem for those of us who also use other H.323 software (such as
gnomemeeting) which specifically requires newer libraries.

Briefly, do I have a chance of reporting this bug with my versions of
libraries, or is chan_h323 completely unsupported if I use anything
other than 1.11.7?

many thanks,
