num-exp
To define how to expand an extension number into a particular destination pattern, use the num-exp
global configuration command.
num-exp extension-number expanded-number
Syntax Description
Default
No number expansions are predefined.
Command Mode
Global configuration.
Usage Guidelines
Use the num-exp global configuration command to define how to expand a particular set of numbers
(for example, an extension number) into a particular destination pattern. With this command, you can
map specific extensions and expanded numbers together by explicitly defining each number, or you can
define extensions and expanded numbers by using variables. You can also use this command to convert
seven-digit numbers to numbers of less than seven digits.
Use a period (.) as a variable or wildcard representing a single number. Use a separate period for each
number you want to represent with a wildcard—meaning that if you want to replace four numbers in an
extension with wildcards, enter four periods.
Examples
The following example expands the extension number 54001 to 14085554001:
num-exp 54001 14085554001
The following example shows how to expand all five-digit extensions beginning with 5 and append the
extension numbers to 1408555:
num-exp 5.... 1408555....
operation
To select a specific cabling scheme for E&M ports, use the operation voice-port configuration
command. Use the no form of this command as an alternative method of configuring two-wire
operation.
