Asterisk <--> Avaya CM 5.2.1 - one way audio

[ktripp]

I have the latest Asterisk 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 Asterisk, but no audio from the Asterisk (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

[trixbox1.localdomain asterisk]#

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

Thanks in advance.

These were my settings quite a while back. We ended up using a PRI interface instead.

[general]
port = 1720
bindaddr = XXX.XXX.XXX.XXX ;IP of the Asterisk
disallow=all
allow=ulaw
dtmfmode=inband
gatekeeper = DISABLE
context=default
progress_setup = 8
progress_alert = 8
progress_audio = yes
fastStart=yes
h245tunneling=yes
srvlookup=no

[Avaya]
type=friend
context=default
host=XXX.XXX.XXX.XXX ;IP of the Avaya C-LAN card
port=1720

I'm way late to this party but...

I have a similar setup with AsteriskNow, and Avaya 5.2.1 CM.

I used cyril's post for my setup which busster linked to.

I also experienced one-way audio and found that the firewall on the AsteriskNow server was not allowing udp 1024-65535 (for the RTP Stream).

I don't know much about trixbox and what distro it uses but I hope this info helps...

There is a good document on setting up a H323 trunk between IP Office and ComMgr. I used the ComMgr settings to get a link up and running. Google it to find.

I successfully setup the h323 trunk and works great. The only issue is that when trying to use a PRI on the Avaya to route calls originating from trixbox sip client it is denied because it is trying to send out video. I have never been able to get around this.
