[cisco-voip] Avaya to Cisco Trunk

[CarlosOrtiz at bayviewfinancial.com]

Has anyone successfully created an H.323 IP to IP trunk between Cisco Call 
Mgr 4.1.x and an Avaya Com Mgr 4.0 system?  I have reviewed documentation 
from both Avaya's website and Cisco's website.  I can currently call from 
an Avaya to Cisco phone but not from Cisco to Avaya.  After about 8 
seconds the calls from Cisco to Avaya just returns a fast busy.  A packet 
capture seems to suggest that after Cisco Call Mgr sends an H.225 call 
setup message to the Avaya CLAN there is no call proceeding, alerting and 
notify messages coming back from the Avaya CLAN.  These H.323 messages are 
seen in a packet capture of a successful call calling  from Avaya to Cisco 
phones.

I have been sent links to online docs but I have tried those already. 
Someone who has done this real world and could provide hands on insight as 
to what the issue may be is what I need.
