I need to place a phone at a locked door and have it ring an internal extension when the handset is picked up. Is this possible? I recall a posting some time ago about the same thing, but cannot find it. Any help will be apreciated.
Currently running old version of call manager 3.2.(2c)spH
This type of Hotdial "Bat-Phone" setup is very possible. Have a look;

How to configure a Cisco IP Phone for Private Line Automatic Ring-down (PLAR) or Hotdial with Cisco CallManager. With PLAR configuration as soon as the phone goes off-hook it dials a pre-configured number. This be done by making use of calling search spaces (CSS), partitions, and translation patterns.
From this good doc;
Hope this helps!
