[asterisk-users] detecting intl. CLI with +

[Eric Wieling]

If you have quotes on one side of the = sign, then you need quotes on the other side.  In your dialplan line you are comparing + with "+".  A plus sign is not equal to quote plus sign quote

exten => _X., n, Set(CALLERID(num)=${IF($["${CALLERID(num):0:1}"  =  "+"]?${CALLERID(num)}:0${CALLERID(num)})})

Subject: [asterisk-users] detecting intl. CLI with +

Hello asterisk users,

I need to convert the CLI received according to national/international format:

55-555-5555 to 055-555-5555 (add 0 in the beginning)
+55-55-555-5555 to +55-55-555-5555 (remains unchanged)

I put the following line in my dial plan:
exten => _X., n, Set(CALLERID(num)=${IF($[ ${CALLERID(num):0:1} = "+"]?${CALLERID(num)}:0${CALLERID(num)})})

But I get these error messages:
[May  2 17:05:43] WARNING[1494]: ast_expr2.fl:468 ast_yyerror: ast_yyerror():  syntax error: syntax error, unexpected '+', expecting $end; Input:
 + = "+"

Can anyone suggest the proper syntax? I tried the + with no quotes, single quotes '+' and double quotes"+" and nothing worked.

Thanks
