Caller ID Feature
The system supports Caller ID. This feature is part of local telephone companies'
Custom Local Access Signaling Service (CLASS). It provides a user with calling
party number information from the central office when a call rings on a loop-start
line connected to a module with Caller ID capability. This information appears
on 4400-Series, MLX, ETR, and MLS display telephones, much like the PRI Automatic Number
Calling number and/or name identification is not available in all areas
or jurisdictions. Check with your local telephone company. The availability
of caller identification information may also be limited by the local-serving
(caller's) jurisdiction, availability, or central office equipment.
The system also supports Calling Party Name, which is part of Caller ID. Calling
Party Name does what its name suggests--it provides the name of the calling
party. A button can be programmed on the multiline 4400-Series, MLX, ETR, and
MLS telephones to toggle between Calling Party Number and Calling Party Name.
When the button's LED is lit, Calling Party Name and not Calling Party Number
information appears and will continue to appear until you press the button again
(the LED turns off).
