[h323plus] Using H323+ for Asterisk's chan_h323

Around October last year
timerChangePipe[]
was replaced by
process.breakBlock;

I suggest you troll through the changelog
http://openh323.cvs.sourceforge.net/openh323/pwlib/src/ptlib/unix/tlibthrd.c
xx?view=log

There has been quite a few changes around october last year.

I hope this helps and we can move ahead with h323plus support in Asterisk.

Simon

Hello Simon,

Good news, chan_h323 is now able to use H323Plus!

:-)

There is only one small problem, it segfaults whenever the chan_h323.so
module is unloaded or Asterisk is stopped (in which case the module is
unloaded again). Otherwise everything is working as expected.

The problem for the segfault, however, is not related to H323. It seems
that it is related with chan_h323's log stream which is a derivative
class of PProcess. Apparently the PWLib/PTLib change had an effect on
this and it segfaults whenever the logstream object is deleted.

I have the feeling that it is related to the timerChangePipe[] array
which is missing in the newest PWLib versions.

I tried to find some documentation about this array but I couldn't find
any. I'd be grateful if you could give me some pointers as to where to
look for relevant information in order to wrap up chan_h323's transition
to H323Plus.
