Network between OXE R9.1 and Aastra Businessphone

OXO-Man · Post by **OXO-Man** » 06 Jul 2010 07:55

Dear specialists,
one of our costumer wants to connect an OXE R9.1 and a Aastra Businessphone via H323-Trunk.
The Businessphone can call into the OXE without an problem. If I call from OXE to the Businessphone the call can´t established. The 4039 shows "busy" on the display.

In the H323-Trace I can see that the call is rejected from the buisnessphone (call from 2000 (OXE) to 301 (businessphone) via H323-Trunk and speeddial):

The admin of the businessphone said that the OXE sends the flag "tunneling:on" so that the businessphone rejects the call.

Can I turn off the "tunneling" on the OXE?

Thank you for your answers!!!!
Best regards

Hi
Probably they are talking about H.245 tunneling in H.225 connection.
Try to enable "Fast start" in IP/IP parameters.

PS. t3 trace is not enough for H.323 troubleshooting. You should take sniffer traces on GD/INT-IP.

Hi Alex,

I´ve just pointed out that the OXE sends an H323-ID to the BP. The ID is the same as the extension number in the OXE. This ID is used in the BP as an password to autorise this incoming call.

The question is:
Is there a feature or flag in the OXE in which I can turn off this H323-ID?

Thank you!

Hmm. I did not get it.
You mean that BP acts as an external gatekeeper for OXE?
