[Asterisk-Users] OpenH323-Channel Q.931-Problems with Gatekeeper

Dear Mailinglist-User

currently we`re working with an IP-PBX, based on Asterisk,  with SIP, H.323
and ISDN-Capabilities. 
SIP and ISDN works fine, but H.323 not.


In our first test, we started to connect Asterisk to an Cisco IOS-Gatekeeper
with the "chan_oh323" (version 0.6.5). 
We successfully tested in/egress calls without any problems.

But when we started to connect our Asterisk with the Gatekeeper (Siemens
Surpass) of an big german Carrier
we noticed some strange problems we couldn`t solve until right now.

The registration with the gatekeeper is successful. But every from and to our
PBX will be cleared/rejected by an Q.931 cause.


Our system-layout looks like:

Debian GNU/Linux 3.1 aka "sarge" with Kernel 2.6.12, i386
Asterisk 1.0.9 (stable)
Pwlib 1.16
OpenH323 1.13.5
Chan_oh323 0.6.6


Perhaps you know some problems with Asterisk and the H.323-Channel.
We tried to compile and test nearly every version of openh323 and chan_oh323,
but it wasn`t successful.




Best regards from Germany,

Sebastian.



Nearby we will post our configs and logs:
