Name a telephone or a line
You can assign names to identify external lines, target lines, and your colleagues’ telephones. During a call, the name (if programmed) appears on the telephone display instead of the external line number or internal telephone number of the caller. You need to start a Unified Manager session to program this feature. For more information about programming using Unified Manager, see the Business Communications Manager Programming Operations Guide.
Telephone names and line names can contain both letters and numbers, but cannot be longer than seven characters. You cannot use the # and * symbols.
Note: You can give the same name to a telephone and a line in your system. Use initials, abbreviations, or even nicknames to give each telephone a unique name to avoid confusion.
Extension numbers
Each telephone in the system has an extension number. The length of extension numbers in your system can range from two to seven digits. All numbers in your system are the same length. Your installer assigns the length of extension numbers, called the extension length. The default extension length is three.
To find out your internal number, use the Button Inquiry feature (≤•‚) from an intercom button. On the T7100 telephone, Button Inquiry shows your internal number followed by the function assigned to the memory button.
