Doorphone Extension (#604 and #605)
Description
Each of these System Programming procedures identifies an extension to which a
doorphone is connected. A doorphone is usually placed near an entrance, to
screen visitors. You can connect up to two doorphones to the system—use
Doorphone 1 Extension (#604) to identify the extension to which the first
doorphone is connected and Doorphone 2 Extension (#605) to identify the
extension to which the second doorphone is connected.
NOTE:
Doorphones should not be connected to an Enhanced Tip Ring only port
since doorphones rely on receiving a forward disconnect signal to
disconnect a call. Connect doorphones to Tip Ring ports, which are the
bottom two ports of any processor or 362EC expansion module. If a Tip Ring
device is connected to an Enhanced Tip Ring only port, a forward
disconnect signal is not sent and ringing is not heard at that port.
Related Features
■ You must use Doorphone Alert Extensions (#606) to identify the
extensions that are signaled when the doorphone button is pressed. Each
doorphone can signal any number of
alert
extensions.
■ To prevent outside calls from being made or received on the doorphone,
use Line Assignment (#301) to remove all outside lines and/or Pool
Extension Assignment (#314) to remove all pools from the doorphone
extension. (Automatic Line Selection for the doorphone extension will be
automatically
set to select intercom lines first.)
■ You can use Message Light On with the doorphone (for example, the
doorphone’s light flashes to signal a delivery person.
Considerations
■ An extension cannot be used for a doorphone and a hotline at the same
time. However, hotlines and doorphones can have the same alert
extensions.
■ Remove voice messaging system mailboxes from doorphone extensions.
■ You cannot bridge two doorphones together.
■ A PARTNER MAIL VS module should be installed in the last slot to prevent
incorrect numbering of the doorphone extensions.
