I have CUCM cluster (1 publisher and 1 subscriber) and I have to configure SIP trunk to telephone provider.
They need my IP address for SIP trunk. Subscriber is the one that is doing call processing (CUCM 6.1.2).
Do I give them IP address of Subscriber or Publisher and Subscriber?
What happenes if my Subscriber stops working and I give them only IP address of Subscriber, will my SIP trunk work?
