When we use Message Notification to HomePhone for a subscriber, we configure some of the unity ports to do Message Notification
Besides on the VoiceMail port at CUCM we have 2 CSSs, the one for the port and the one for the DN of the port
The CSS for the port has to be public for susbcribers phones to get there
The CSS for the DN of the port is normally the restricted one.
Which of those CSSs does Unity uses when Message Notification to a HomePhone?
VM ports use in 1st place the one from the port and then the one from line, opposed to the behavior of phones.
if this helps, please rate
