[OpenSIPS-Users] Strip prefix

[Ben Newlin]

It looks right to me. The error you get when changing repl_exp to “\1” implies to me that it is causing the dpid to fail to load from the database at all due to some syntax issue. Is you database escaping or converting the “\” maybe?

I’d recommend increasing the logging verbosity of opensips and doing a module reload and the test scenario and see what the logs say about why it isn’t matching.

Yes i change it all


dpid = 17

pr = 0

match_op = 1

match_exp = ^770555.+

match_flags = 0

subst_exp = ^770555(.+)

repl_exp = \1

without  \1  im able to complete the call but prefix still there and when i add the \1  on repl_exp i get the error

Did you make all the changes I suggested or only changed the repl_exp? I detailed changes needed to the match_exp and subst_exp as well.

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
