I need help with finding a door entrance system

["camman" <camman@xxxxxxx>]

I am familier with Aiphone, but I dont think this is an Aifone application.
Here is the deal.  Customer is looking for a system where they have a panel
at the front door, person presses button and it rings in office.  Here is
the kicker... they want it to ring on their office phone and allow anyone
with a desk phone to open it.  I really just need a dialer in the outside
panel I am guessing that rings the office number. .. then they press * and
it unlatches the door.  I know they make this.. but no idea who makes it.

thanks..
