I am trying to set up an h323 trunk between our Avaya s8700 and Asterisk 1.4.x. I have been able to establish calls in both directions over this new trunk, but the majority of the time multiple connections over that trunk drop all calls. Does anyone have any ideas what the problem might be?
I have appended my Avaya and Asterisk configs as well as output from the Avaya trace operation.
Here are a series of trace’s taken by the Avaya PBX:
-------------------------------------------------------------------------------------
This shows extension 4022 on Avaya calling 6699 on Asterisk over trunk group 2. 10 seconds later extension 4001
on Avaya calls 6699, after hearing 10 seconds of silence both calls go to a quick busy signal.
