1.17.1  Doorphone Call
Description
It is 
possible to connect doorphones directly to the PBX. When a visitor presses the call button on a doorphone,
the doorphone calls a preprogrammed destination (extension or outside party). In addition, extension users
can dial the preset number of a doorphone to call that doorphone.
