Doorphone Call
Description
Your system supports a doorphone. 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 originate a call to a doorphone.
Conditions
• It is needed to install a user-supplied Doorphone.
• A maximum of three doorphones can be connected to the system.
• 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 cancelled.
• 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.
