With the Hot Line Service, the user of a single-line telephone can automatically connect to a preassigned destination when the user goes off-hook. You can assign the following numbers as a Hot Line Service destination:
An attendant
An extension
A Feature Access Code (FAC)
A public telephone number
A private telephone number
The Hot Line Service destination number must be stored in an Abbreviated Dialing list. When the user goes off-hook, the system automatically routes the call to the stored number, and completes the call as if the user dialed the call.
If an attendant number is the Hot Line Service destination number, the system automatically routes the telephone user to the attendant.
If the appropriate FAC is stored with the number in the Abbreviated Dialing list, the system uses Automatic Alternate Routing (AAR), automatic route selection (ARS), Data Privacy, or Priority Calling.
If the Public Network Access code or the Private Network Access code is the number stored in the Abbreviated Dialing list, the system connects the user to the outside number.
A Direct Department Calling (DDC), a Uniform Call Distribution (UCD), a Terminating Extension Group (TEG) extension, or any individual extension within such a group, can be a Hot Line Service destination.
Hot Line Service retains the way that a user receives calls. Calls to a user with Hot Line Service are controlled by the Class of Restriction (COR) that you assign to the user extension. Hot Line Service does not affect the recipient of the call.
