[cisco-voip] Need advice to unlock doors

[Sandy Lee]

Hi,

I've been asked to integrate our CM 7.1(3) with an iStar Pro system which controls electric strikes on doors. They want to be able to unlock doors from an IP Phone. Let's say a visitor's at the front door for me, so he lifts the IP Phone right by the door and dials my number. Then, I input a code or a softkey or anything that will trigger a relay, which will unlock the door.

I absolutely don't know how to do this. Any advice will be greatly appreciated!
Regards.

Sandy.
