Integrate Asterisk with another IP PABX?

Any one has try to integrate/connect Asterisk with others IP PABX such Aavya, Alcatel using H.323 protocol? Thanks.

ooh323.conf

I commented out all of the other peers stanzas and added the following for my IP Office:

[IPO]
type=peer
ip=10.12.0.50
port=1720
disallow=all
allow=ulaw
allow=g729
allow=gsm
canreinvite=no
dtmfmode=h245signal

The only other uncommented lines are:

port=1720
bindaddr=10.1.1.100
faststart=yes
h245tunneling=yes
gatekeeper = DISABLE
disallow=all
allow=ulaw
allow=g729
allow=gsm
dtmfmode=h245signal

Then created a custom trunk with a Dial string of:

OOH323/[email protected]

I’ve a VPN connecting the two sites so it’s all private IP’s, I didn’t have to worry about any NAT issues.

Initially I had DTMF mode at RFC2833 but the IPO did seem to pick up the digits.

I’m not sure how much intergration you want. But I’m able to connect calls betwwen an Avaya IP Office and my asterisk box using H.323 over a LAN-toLAN VPN.

Do you mind to give me the setting on Asterisk? Thanks.

Yes the same configuration is working fine with me too. But When I try to call from Asterisk extension to reach outside landline number using the avaya trunks it thows an error.

I have an avaya IP office in one location and a private T1 between locations. I cant find the ooh323 on asterisk. I created a trunk for my avaya in the freePBX. Do I have to create a ooh323.conf? Where am I going wrong with this setup?
