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: + = "+" ^ [May 2 17:05:43] WARNING[1494]: ast_expr2.fl:472 ast_yyerror: If you have questions, please refer to https://wiki.asterisk.org/wiki/display/AST/Channel+Variables [May 2 17:05:43] WARNING[1494]: func_logic.c:192 acf_if: Syntax IF(<expr>?[<true>][:<false>]) (expr must be non-null, and either <true> or <false> must be non-null) [May 2 17:05:43] WARNING[1494]: func_logic.c:193 acf_if: In this case, <expr>='', <true>='+55555555555', and <false>='0+55555555555' Can anyone suggest the proper syntax? I tried the + with no quotes, single quotes '+' and double quotes"+" and nothing worked. Thanks
