[OpenSIPS-Users] Strip prefix

[Ben Newlin]

There’s a few issues.

1. You are missing a “.” in your match_exp. The way you have it written will only match repeating digit 5 after the prefix.
2. Your subst_exp is too greedy. The wildcards in the first grouping will make that grouping match the whole string, and there will be nothing left for the second grouping (or it won’t match at all because of the + in the second grouping, not sure). If you are trying to match a fixed-string prefix you don’t need wildcards for that. You also don’t need to capture that grouping, since you aren’t using it in the replace.

Try this:


dpid = 17

pr = 0

match_op = 1

match_exp = ^770555.+

match_flags = 0

subst_exp = ^770555(.+)

repl_exp = \1
