Returns the value of the given channel varible and understands complex variable names and builtin variables, unlike the GetVariableCommand.
You can also use this command to use custom Asterisk functions. Syntax is "func(args)".
Returns 0 if the variable is not set or channel does not exist. Returns 1 if the variable is set and returns the variable in parenthesis.
Example return code: 200 result=1 (testvariable) Available since Asterisk 1.2
