Asterisk cmd Cut - VoIP-Info

Synopsis

Cut(newvar=varname,delimiter,fieldspec)

As of Asterisk 1.2 this command has been depracated. It has been removed as of Asterisk 1.4.
Use the function Cut instead.

Cut(newvar=varname,delimiter,fieldspec)

newvar: this variable is set to the result string
varname: variable you want cut
delimiter: defaults to –
fieldspec: number of the field you want (1-based offset), may also be specified as a range (with -) or group of ranges and fields (with &)

The delimiter must be a single character. When multiple characters are specified, only the first character is used.
To specify a comma as a delimiter, escape it with a backslash: Cut(foo,\,,1)
When multiple fields are specified, they are joined back together using the delimiter specified.
This command is most useful when dealing with fields that are variable width. For fixed width string processing, use the builtin variable substitution.
The application Cut has been deprecated in 1.2 in favor of the builtin function CUT.

The varname parameter must be a variable name, not a string value. This is unusual syntax. So:

exten => s,1,Cut(foo=bar,,2) ; This is correct syntax
exten => s,1,Cut(foo=${bar},,2) ; This is invalid syntax

exten => s,1,Set(foo=1-2-3-4-5)
exten => s,2,Cut(foo=foo,,1-3&5)

foo is now set to 1-2-3-5
