Doorphone/Internal Hot Line Phone/Emergency Phone (#604) - AT&T PARTNER Installation And Use Manual

Doorphone/Internal Hot Line
Phone/Emergency Phone (#604)
Description
This telephone option assigns an extension as one of the following:
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 is signaled.
Internal Hot Line Phone. When a person lifts the handset of an internal hot
line phone, a predetermined alert extension is signaled. An internal hot line
phone should be a standard phone; the alert extension can be any type of
phone.
Emergency Phone. When a person lifts the handset of an emergency
phone, a predetermined outside number is dialed automatically. The
emergency phone number might be, for example, the fire department,
police, or a poison control center. An emergency phone should be a
standard phone.
After you assign an extension with this option, you must also set up the alert
extension(s) and/or store the outside emergency phone number(s) on the top,
leftmost Auto Dial button. See "Changing Settings" on the next page.
Related Features
Make sure there are no call restrictions assigned to an emergency phone. See
Outgoing Call Restriction (#401).
Considerations
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 hot line 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 hot line phones can have the same alert
extensions.
You cannot assign a doorphone, internal hot line phone, or emergency
phone to extensions 10 and 16. You can assign a doorphone, internal hot
line phone, or emergency 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).
Valid Entries
Extensions 11–14, 17–21, and 15 if it is not activated for Music On Hold
5-14
