I've tried everything to control my Cisco IP Communicator softphone 7.0 via the Cisco Personal Communicator7.0
In the CUPC Show server health the message behind softphone is "connecting (primary).It is not possible to Place a Call (Phone not Available) it is greyed out.
Thanks in advance!
I've attached 2 screenshots
Just for your information:
1) You should NOT change the hostname in OS administration. It would cause more problem than you had expected.
2) If you'd like application use IP address to contact CUCM, you should go to CUCM Admin web page > System > Server. Change the hostname there to IP adress.
