DID Number all numbers

Hello, I have a doubt about DID Number. How to identify the DID Number? I can leave the option active for all incoming DID Number go to a specific number?
Thank you

On an inbound route, if you do not specify a DID Number, all incoming calls will route to that entry. We call it the “Any/Any” (No DID, no CID) route and you should have one for any PBX.

If you do this exclusively (no DID based inbound routes), you will get notices in your /var/log/asterisk/full log file about “Maybe you should set up a matching DID” or something similar). As you find these, create new DID based routes for these numbers and set them up according to the information from the log. This way, there is no ambiguity about what your provider is sending and you can match it perfectly.
