Doorphone Call
Description If a visitor presses the doorphone button, pre-assigned extensions
are rung. The extension who answers the call can talk to the visitor.
It is possible for any extension user to call a doorphone.
Conditions • One doorphone can be installed.
• It is necessary to program the extensions that can receive calls from
each doorphone during day and night mode.
• If no extension user answers an incoming doorphone call within 30
seconds, the call stops ringing and is canceled.
• While engaged on a doorphone call, any extension user can open the
door from the telephone to let the visitor in (Door Opener). This
requires a user-supplied door opener.
• If the doorphone call is placed on hold, the Music on Hold is not
available.
