Unable to make calls frequently


Hi guys im using UCM6102, and GXV3240, my GXV3240 always unable to make calls but its ok after i reboot UCM6102, anyone have any idea what’s the problem and solution to it?


Need more detail of the set-up, any message that is heard, what type of connection for telephone service, is the phone remote or local to the PBX, if there is more than one phone and if they too have the issue or only yours, etc.

The question is simply too vague.
