[cisco-voip] Need advice to unlock doors

[Eric Butcher]

There are various adaptors for traditional telephony systems that provide this.  It is typically a contact closure device that hooks to a station port (FXS).

You would then assign a DN to the FXS port, and make sure that phone outside the door can't dial it...  Employee dials the number to unlock the door, and hangs up.  You could use a speed dial.

This is the most common implementation of the concept that I see.

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.
