Doorphone. A doorphone is an auxiliary device that usually is installed
near an entrance for screening visitors. When a person presses the
doorphone button, a predetermined alert extension or all system extensions
are signaled.
Internal Hotline Phone. When a person lifts the handset of an internal
hotline phone, a predetermined alert extension or all system extensions are
signaled. The hotline phone should be a standard phone; alert extensions
can be any type of phone.
External Hotline Phone. When a person lifts the handset of an external
hotline phone, a predetermined outside number is dialed automatically. The
hotline phone should be a standard phone.
After you assign an extension with this option, you must also set up the alert
extension or store the outside External Hotline Phone number on the top,
leftmost Auto Dial button. See “Changing Settings” on the next page.

Make sure that any call restrictions assigned to an external hotline phone do not
prevent the number from being dialed. See Outgoing Call Restriction (#401).
Considerations
Under certain conditions of heavy system usage, the external hotline phone
may be unable to dial the predetermined outside phone number
immediately. If you do not hear dial tone or dialing noises when you attempt
to use the external hotline phone, hang up for about 20 seconds and try
again.
Use this option for all three phone applications. The system differentiates
the applications by the phone connected to the extension and the number
stored on the Auto Dial button.
Each doorphone and internal hotline phone can ring a specific alert
extension or all system extensions.
If an alert extension is a system phone, the signal will be a distinctive
ping-pong sound to distinguish it from other calls. If an alert extension is a
standard phone, the phone will receive normal intercom ring.
Doorphones and internal hotline phones can have the same alert extensions.
You cannot assign a doorphone, internal hotline phone, or external hotline
phone to extensions 10 and 16. You can assign a doorphone, internal
hotline phone, or external hotline phone to extension 15, provided Music On
Hold is not activated.
You can assign these special phone applications on up to 10 extensions (9
if Music On Hold is activated).
