Use this feature to identify an internal hotline extension and its alert extension. When a user lifts the handset of the hotline telephone, the alert extension rings. You can set up several hotline and alert extension pairs. The alert extension can be the same or different for multiple hotline extensions.
Use a single-line telephone as the hotline telephone since this feature makes use only of the telephone’s intercom. The alert extension can be any type of telephone; or it can be the loudspeaker paging system so the hotline telephone can be used to make announcements over the loudspeaker.
For example, a supermarket installs a hotline telephone at its meat counter. When a customer uses the hotline telephone, the butcher’s telephone rings. If the loudspeaker paging system is programmed as the alert extension, a sales clerk could request a “price check” over the loudspeaker simply by lifting the handset of the hotline telephone.
•The same extension cannot be assigned as an internal hotline extension and a door phone extension. Assigning a door phone extension as an internal hotline extension cancels the door phone setting.
•You should not assign hotline telephones to either of the first two extensions in the system.
•The hotline telephone can receive transferred calls (but the user at that extension should not pick up the handset until the telephone rings).
•To prevent outside calls from being made or received on the hotline telephone, use Line Assignment to remove all outside lines.
•Set Automatic Line Selection for the hotline extension to intercom only.
•Remove hotline extensions from Night Service Group Extensions, Calling Group Extensions and Hunt Group Extensions.
•Use External Hotline to identify an extension that automatically dials a programmed outside number when a user lifts the handset.
