[SR-Users] Issue in Dialplan Module

Sat Aug 5 07:34:42 CEST 2017

Thanks a lot for the Detailed Explanation.

I am Beginner to Kamailio, As per Your Suggestion I have used the below
Rule:

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:

But the First three Digit is not Removed. Please find the below log:
