Re: [SR-Users] Issue in Dialplan Module

Ok, so clearly you have not tried what Daniel suggested... *IN a regexp ^ matches the beginning of the line/string, and $ matchesthe end. So "^000$" only matches exactly "000" and not "000xxxx"Remove the $ to match strings begining with 000.* Rules: ====== dpid: 1 pr: 1 match_op: 1 match_exp: ^000$ match_len: 0 subst_exp: ^0000$ repl_exp: attrs: Can you see you still have the $ char at the end of match_exp and subst_exp? To begin with, do you know how regular expressions work? Because that is the first thing you need to know to correctly use the dialplan module. That said you need a match expression, a substitute expression, and a replace expression... Try with: Rules: ====== dpid: 1 pr: 1 match_op: 1 match_exp: ^000[0-9]+$ <<<<<<< This will trigger a match on any number that will start with three zeros. match_len: 0 subst_exp: ^000([0-9]+)$ <<<<<<< If the match_exp is found, then create a group with the desired part of the number, in this case, everything after the three zeros. repl_exp: \1 <<<<<<< \1 is a back reference to group 1, in this case the number you selected in subst_exp, without the three zeros. attrs: What isn't clear to me is that 91 you are talking about in your email, you might have to exclude/include that in your regex. Have a look at https://www.kamailio.org/docs/modules/devel/modules/dialplan.html#dialplan.… You have a couple examples that might make it more clear. Let me know if it helps. Joel.
