Asterisk - Avaya one way audio problem - weird

I have the latest trixbox setup and trunked to an Avaya CM 5.2.1 with a H.323 trunk.
I can make incoming and outgoing calls fine. I have audio from Avaya to the trixbox, but no audio from the trixbox (sip client) to the Avaya.

Here is my ooh323.conf config:
[general]
port=1720
bindaddr=10.1.122.7
faststart=yes
h245tunneling=no
gatekeeper=DISABLE
disallow=all
allow=ulaw
dtmfmode=inband
context=from-internal
e164=100
h323id=ObjSysAsterisk
callerid="Asterisk PBX"
progress_setup = 8
progress_alert = 8

[avaya]
type=peer
;type=friend
context=from-internal
host=10.1.105.16
port=1720
disallow=all
allow=ulaw
canreinvite=no
dtmfmode=inband

When I do a packet capture on the trixbox, it is almost like there is no rtp stream from the trixbox to the Avaya. I see from the Avaya, and to/from the sip client. It makes me think that the bridge between the sip phone to the h323 trunk is no existent or broke.

When looking at the h323log on the trixbox this is what it shows during a one-way audio call.
[trixbox1.localdomain asterisk]# tail h323_log
11:38:50:539 ooFindLogicalChannel, checking channel: 1:transmit
11:38:50:539 ooFindLogicalChannel, comparing channel: 1002:transmit

11:38:50:539 }
11:38:50:539 ERROR: unbalanced structure
11:38:50:539 Error:Invalid Connect message received. (outgoing, ooh323c_o_106)
[trixbox1.localdomain asterisk]#

I've scoured this forum and the internet. Last ditch effort was to post here. Any thoughts?

Thanks in advance.

If memory serves me right

If memory serves me right several RTP settings are on the Avaya box. One of them provides media anchoring that solves this issue.

Thanks for the replies

Thanks for the replies guys.

I've never heard of 'media anchoring' on the avaya, but that doesn't mean anything. During a packet capture, there was no stream or data packets being sent from the Triax box back to the pbx, it almost seems like it does not know how to get to the avaya h323 trunk.

The Avaya is sending the

The Avaya is sending the wrong IP address in the H.323 message.

Look for RTP options on the Avaya, it's been awhile, I am sure I posted about it years ago. Probably on this site or FreePBX.org
