Description:	I seem to be either doing this incorrectly, or it is not working as intended: exten => 2228,n,Set(shiz=${CUT(1234abcd,a,2)}) exten => 2228,n,NoOp(shiz=${shiz}) Results:    -- Executing Set("SIP/tello.com-08178718", "shiz=") in new stack    -- Executing NoOp("SIP/tello.com-08178718", "shiz=") in new stack   Expected results: $shiz=bcd I've tried the following, with the same results: exten => 2228,n,Set(shiz=${CUT(1234abcd,"a",2)}) exten => 2228,n,Set(foo=1234abcd) exten => 2228,n,Set(shiz=${CUT(${foo},a,2)}) This originally extended from my attempts to use the "@" sign as a field separator in SIP manipulations, but boiled down to either my continued misunderstanding of the CUT function, or a bug.  I also tried using the (older) app_cut, with similar failure results.  I have also tried different field delimiters, with no valid results (1,3)
Comments:	By: Tilghman Lesher (tilghman) 2005-11-27 22:31:29.000-0600 As noted in the help and on the Wiki, the CUT function takes a variable NAME as an argument, not a STRING.  By doing variable interpolation in the dialplan, you are handing the function a string, not a variable name. Your example would work if there was such a variable as ${1234abcd}. By: Tilghman Lesher (tilghman) 2005-11-27 22:33:11.000-0600 Note the typical example is the use of the CHANNEL variable, i.e.: ${CUT(CHANNEL,-,1)}
