I have a 6608 blade with CallManager 3.3.3. Problem is when an incoming call
is destined for Unity. As soon as the call from PSTN reaches a Unity VM port
through the 6608 gateway, the caller gets a fast busy. Call is disconnected
on the 6008 gateway with cause code 80E5 which means "Message not compatible
with call state or protocol error threshold exceeded". The messaging
sequence between 6608 and PSTN is as follows:
Setup <--
Call Proc -->
Alerting -->
Connect -->
Status <--
Connect_Ack <--
Status <--
Disconnect -->
Release <--
Release-Comp -->
If you call Unity from an IP Phone, it works fine.
If you call an IP Phone from PSTN through the 6608 gateway, it works fine.
If an IP Phone is forward all to Unity, and you call the IP Phone, as soon
as the call reaches Unity, caller receives fast busy.
Any ideas why this could be happening?
Thanks,
Partha
