Thanks, that works.
I thought this is only relevant if DID is configured and because both routes have no DID, I ignored it.
I had a workaround (use dial pattern _[+0-9]! instead ANY) but your solution is quite more elegant
The other way to solve it is to strip the internationalization information from the inbound call and normalize your numbers in a way that allows people to actually enter the numbers from the keypad. The “generally accepted” way of doing that is through a context like “from-pstn-e164-us” or “from-pstn-e164-gr” contexts in your inbound trunks.
