Unsupported outgoing call from Yeastar to 3cx via DID numbers

[uniscanadmin]

continuing the topic https://www.3cx.com/community/threads/how-to-get-the-callers-extension-number.136774/

Now we need to implement a return route so that 3CX displays the caller's number from Yeastar and headed to the called subscriber's number

I've already tried different connections, but almost nothing works.

If I do this through the Slave Bridge, then for some reason authorization in 3CX does not work for this trunk.

And if I select the "Asterisk" trunk, the call goes through and even the caller's number is displayed, but I can't figure out how to route it via DID.

How to configure an Asterisk trunk to route calls to internal numbers based on the To field value?

I think I found a solution https://www.3cx.com/blog/call-flow-scripts/call-routing-did/

but this is a hand-face

The question remains: how to display the caller's name?

The result is slightly improved.
I adjusted the script using AI.
Since the DID number matches the called party's extension, I don't need an additional JSON file with the number mapping.

Can anyone tell me how to resolve the issue with displaying the caller's name using a script?
The name is in the "from" field.
