I am running CUCM V 11.0. I have an issue where calls are being dropped when the receptionist transfers a call to another internal extension.
It doesn't happen on every call, but more often than not. It doesn't matter if it is a blind transfer or a warm transfer.
I am attaching a call example from this morning.
Calling number 6784950050
Answered by ext 5600
Transferred to ext 5624
User reports call rang at the transferred ext but the call dropped as it was being answered.
I would appreciate any guidance from anyone.
