Asterisk with Avaya CM on H323 trunk

Asterisk Asterisk Support
1

Hi,

I need to resolve problem the following problem. I try to install an Asterisk with Avaya CM3.0 connected via H323 trunk. It is work when I used veri old version of asterisk 0.7.x (installed from debian package with asterisk.oh323). Now I compile the last version 1.2.7.1 and the 0.7.3 OH323 driver, but unfortunately the H323 trunk doesn’t work with CM, but work well with other Avaya PBX (IP office).

When I call from Asterisk (a sip extension) to a CM IP extension, the extension rings but I allway give ‘reason 8 (Transport failure)’ in the Asterisk CLI.
If I call from CM to Asterisk sip, the Sip extension rings, but no voice.

Please help who use Astersik with Avaya Definity or Communication Manager.
All solution will be good not only OH323 driver.

The problem was caused by Faststart option, because it doesn’t work correctly in 0.6.7 and 0.7.3 OH323 driver.

You can found soution in the folowing link

skylab.inaccessnetworks.com/man … .php?id=90

After recompileing the driver works with avaya CM.
