[Asterisk-Users] h.323 debian sarge problem - Could not open sound channel

[Mészáros Mihály]

Hello!

I use debian sarge i386 with the following packages.

asterisk 1.0.1-1                
libopenh323-1.13.2  1.13.5.4-4  

I get the following error if i want to connect with a h.323 ep to asterisk.

Releasing session 1

I read the asterisk source in chan-h323 readme.txt that it works only 
with pervious version of libopenh323.
I'm very interested to make it working with the current debian openh323 
package 1.13.5.
Anybody is working on it?
I tried to see h323ep.cxx(2143) it seems
I am new with asterisk. :-(
I read that chan-h323 use the RTP of  asterisk but it use codec  
libopenh323 ? Is it true ?
If i am not wrong it use the libopenh323 to only create the connection 
and than it create own rtp but it use libopenh323 codec?
Or it use asterisk codec?
Please if you can please help me to solve this problem.

Thanks Lot!
