I have created an H.323 trunk btw the Avaya PBX and CCM5.1. The trunk in Avaya side shows "in service/Idle" but I can't see if in CCM side is up too. I have a route pattern 61XX which matches the extensions in Eden (6100-6199)and can see using the digit analyzer it matches 61XX route pattern and hits the h.323 gateway configured to connect to Avaya PBX. When I dial 4 digits extension like 6111 which is a valid extension in Eden (US) I hear a busy tone. I have the following:
1)PT-Cisco-Avaya (the partiion used for route pattern 61XX)
2)CSS-Cisco-Avaya which contains the PT-Cisco-Avaya and PT-Phones in which all phones are.
3)The CSS for the H.323 GW is also CSS-Cisco-Avaya.
4)The codec used in the region is G.711 in both sides.
5)The MRG is also configured
Could you please let me know if I am missing something?
