Hi Everyone,
We have recently noticed that, at least for one of our branch site, call forward (CFWA, CFNA, CFB) or direct call to Unity are *sometimes* not answered by Unity Connection.
The call keeps ringing (on the phone, the pilot point number is shown) but is never answered. It happens randomly and many users are impacted.
I first though it was a port registration problem, but all ports look registered in CM.
Using the Cisco Unity Port Monitor show no incoming call (whyle other call are getting answered by CUC at the same moment). We have at least 100 ports free so it is not a capacity problem, and I believe I would hear a busy tone, instead of the ringback.
This is very frustracting and hard to test has the behaviour can change from one call to another.
Any idea where I should look ?
Thanks
