SOLVED Outbond not working with regex: INVALID_NUMBER_FORMAT

[Tobias.F]

Hello,

after having fixed my type in the inbound routes (link), now I got stuck at the outbound routes.

If I simple use the following as dialplan expression, all is working fine:

^$

But if I use this one, it is not working:

^(|49|\+49|0049|0)[1-9](\d*)$

What I want to achieve is to catch local German numbers in all possible variations. Maybe this regex is not a masterpiece of art but it should be correct and all my tests on online regex tester are OK. Dialing the same phone number as before, I get an error

c7df482e-5673-4ee0-b63c-f9a65a3f310a 2024-03-29 16:06:41.505901 95.07% [INFO] mod_dptools.c:3635 Originate Failed. Cause: INVALID_NUMBER_FORMAT

Any idea what is wrong with my regex?

You have two capturing groups there so the contents of \d* will end up in $2.

The first alternative of your first capturing group will always match nothing (a zero length string), that may be why you are seeing the INVALID_NUMBER_FORMAT error.

You can make your first group non-capturing with ?: i.e. (?:|49|0049)

Thank you.
I was not aware about the concept of capturing groups. My understanding was that this is just is a filter if the dial plan applies.

I just put the whole regex in brackets to get all in the first capturing group.

^((|49|\+49|0049|0)[1-9]\d*)$
