Ip Communicator Service Issue


I just finish installing CUCM v10.5 and I registered 2 Ip communicator client. They are register and I'm able to call from one to the other but the screen is stuck to "Select Service..." when I press Exit it bring me back to the same screen. It's kind of annoying, if anybody could help me with that it would be very appreciated.


I have attached an image with the screen I'm stuck on.

Thats because you havent subscribed to any service. Go to the phone in UCM, on the top right corner, there is a related links section, click the drop down and select subscriber/unsubscribe services.

The problem is due to the

The problem is due to the "idle timer" in the phone configuration page which you will probably find it to be set to 1 second. Most probably you didn't set this, but it came from the newly introduced "Universal Device Template", which get applied on auto-registration and some other features. If you want to avoid this problem, modify the parameter on the template, under User Management > User/Phone Add > Universal Device Template.
