Hi,

as this is my first post, I must say hello and thank you all for developing the
ooh323 module. I need to link an old Alcatel PBX with Asterisk and
without you I wouldn't be able!

Next, my question/problem. As I said, I'm trying to link an old
Alcatel OmniPCX office with Asterisk (actually, trixbox) using h323.
So far, I'm able to call from Asterisk to extensions on the Alcatel
without any problem.

But... I'm not able to call from an Alcatel extension to a Trixbox
extension. The call seems to be established, and the Asterisk phone
rings, but as far as I answer the call it gets disconnected. I think
this is a codec problem, since in the h323.log I see:

17:32:38:551  Handling H245 message. (incoming, ooh323c_3)
17:32:38:551  Deleted TCS Timer. (incoming, ooh323c_3)
17:32:38:551  Opening logical channels (incoming, ooh323c_3)
17:32:38:551  Looking for matching capabilities. (incoming, ooh323c_3)
17:32:38:551  ERROR:Incompatible audio capabilities - Can not open
audio channel (incoming, ooh323c_3)
17:32:38:551  ERROR:Failed to open audio channels. Clearing
call.(incoming, ooh323c_3)
17:32:38:551  Finished handling H245 message. (incoming, ooh323c_3)
17:32:38:551  Finished handling tunneled messages in
Facility.(incoming, ooh323c_3)
17:32:38:551  In ooEndCall call state is - OO_CALL_CLEAR (incoming, ooh323c_3)

Also, I can call a SIP extension using a H323 softphone, so I seems
that ooh323 & Asterisk are working.

Maybe the Alcatel PBX is offering the wrong codecs, or with a name
other than what ooh323 expects? Using g729 (free version,just to test)
does also not work. Any ideas? This is my ooh323.conf. I've no peers
defined, maybe I've something wrong in the config?

[general]
bindaddr=0.0.0.0
faststart=yes
h245tunneling=yes
gatekeeper = DISABLE

;The codecs to be used for all clients.Only ulaw and gsm supported as of now.
;Default - ulaw
; ONLY ulaw, gsm, g729 and g7231 supported as of now
disallow=all
allow=ulaw
allow=g729

context=from-internal
dtmfmode=rfc2833


Thank you very much in advance.
