Inbound calls not working

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:

ooh323 rtp/rtcp ports

Hi,

I am using ooh323 v0.8.3 in an embedded linux client (uclinux 2.4).
I am having some troubles in H245 negociation with the rtp/rtcp ports and a
specific gateway:
when I am trying to establish the logical channel, I get
My client -> gateway : OpenLogicalChannel , Tsap Id = 14035
gateway -> My client : OpenLogicalChannel , Tsap Id = 28001
My client -> gateway : OpenLogicalChannelAck , MediaChannel Tsap Id (RTP) =
14036, MediaControlChannel Tsap Id (RTCP)  = 14037
gateway -> My client : OpenLogicalChannelAck , MediaChannel Tsap Id (RTP) =
28000, MediaControlChannel Tsap Id (RTCP)  = 28001

After this negociation, the gateway tries to send RTP in port 14034 that is
closed.

The problem seems to be that ooh323 send a first port on the OpenLogicalChannel
request (14035) and changes the port in the OpenLogicalChannelAck (14037).
If I enable some traces and if I look in ooh245.c, it seems that I call
AddNewLogicalChannel(...) two times ( first time on the OpenLogicalChannel
request and second time when I receive the remote OpenLogicalChannel request)
that's why I acknowledge with port 14037.
Has anybody ever had this problem ? Is it allowed to send a
OpenLogicalChannelAck with other ports that the ones sent in OpenLogicalChannel
?
Thanks a lot if anybody can help.

Stan
