Hello,  My client has CUCM System version: 7.1.5.31900-3. He have to change IP address of CUCM. He use IP address as hostname. Should he have to rehost license file after reip?  

I looked through this forum but didn't find the answer.Is it possible for CUCM 7.0 to display on IP Phone 7942/62/75 a name from Personal Directory instead of phone number for incoming call from PSTN?
