Setup at Location A:
IP Phone Ext 111---CCM Cluster--Voice GW---PSTN
IP PHone 111 can call PSTN from Location A.
There are other phones at Location B registered to same CCM Cluster but those phones can't dial PSTN.
Now if someone physically moves IP Phone 111 to location B, the user can dial PSTN as usual.
Is there a way to prevent IP Phone 111 from making PSTN call when moved to location B without changing any config on CCM?
Thanks for your time.
