Okay, this is what I want to do:
I live in a big apartment complex with a main "door king" in front (the building is locked). From the door king you can call up to an apartment. The person can then pick up the phone and press 9 to open up the front gate and let whomever is in front in. I would like to automate this for myself. So I can call up to my apartment, with nobody home, and open up the door. Keys are a thing of the passed.
Thanks.
