Subject: [asterisk-users] parsing issue
I get an error when I execute this code
exten => rejected,n,Hangup($[-1*${Z}])
May 2 13:42:09] WARNING[23128]: ast_expr2.fl:468 ast_yyerror:
ast_yyerror(): syntax error: syntax error, unexpected $end, expecting '-' or
'!' or '(' or '<token>'; Input:
-1*
The variable "Z" has a negative number, which is the code that I need to use
in the hangup.
Any idea how can I do this? There is no ABS() function in Asterisk. I already
filed a request for it but it turns up that it will cost me money. How can I
remove the sign from a number?
