Display Operation
Caller ID information is displayed on 4400-Series, MLX, TransTalk 9031/9040, Business Cordless, ETR, and MLS display telephones. You can display Calling Party Name on a 4400D telephone by dialing #763. A QCC can display the Calling Party Number but not the Calling Party Name.
The display shows No Caller ID when the call is answered before the Caller ID data arrives, when the Caller ID data is corrupted, or when no Caller ID data is sent from the central office.
Private may appear if the caller has subscribed to a central office service that blocks call identification. The phrase Out of Area appears on the display when the call originates from a line or caller area without Caller ID or caller information, or sometimes from areas run by local service companies other than your own.
Hyphens are inserted between the digits--for example, 555-1234 for a 7-digit telephone number and 916-555-1234 for a 10-digit telephone number.
See "Display" for more information.
