That's an interesting solution. Caveats :
- To have a door phone and door release would require 2 ports on the pbx unless you don't want to be able to call the doorphone, or release the door while the caller is still on the line. - if the doorphone is a regular phone and uses this method, anyone could simply apply 120VAC to the phone jack for it and presto, the door opens. > > For a door release, I have a cheap radio-shack device which is supposed > to light up a lamp when a phone rings.
