Call page fails?

[g4l]

Any ideas as to why call page would fail? Have a system that used to do call pages just fine, but a couple months ago it stopped working out of the blue. No upgrades on it have been done in some time, and the extensions we try to page work just fine when dialed directly. Phones are Yealink T20s, 3cx version is 11, and running Win7 Pro.

My experience with this problem has been the "Conference service" has stopped for some reason. On the 3CX console, go to system services and check the status to see if the Conference service is running. I manage a V11 system that has stopped twice in the past year. Restarting just that service corrects the problem.

You should also notice under the "system extensions" section that the 700 numbers assigned to conference extensions are unregistered.
