Direct outgoing calls to DID numbers back to 3CX server

[Zvjer]

So what my customer wants is that when they call ANY of the DID numbers on their SIP trunk that 3CX understands this and skips ALL the outgoing rules and just passes the call internally by checking the inbound rules. Is this possible?

A couple way that this can be done
You can create a loop trunk, that uses the outbound rules to send the call right back in to 3CX that then uses the DID rules to route that call. the disadvantage being that each call counts as two.

See...
https://www.3cx.com/community/threads/internal-extensions-dialing-did-loop-out-and-back-in.40588/

You can assign a SIP ID of the DID number (the entire number as dialled) , to the destination extension. Outbound rules will be ignored, and the call will route to that extension.

.. and if you decide to use the SIP ID, have a read through this is, you are using version 16....
