Changing Display Information of Incoming Call

[Zalhera]

We're trying to find a way to manipulate the display name of an incoming call and replace the shown caller number with a customer name.
I know that this is possible by adding the customer's information to the contacts, but we do not want to add all the customer data in there.
We also tried this with the CRM integration, but unfortunately the contact lookup creates entries in the contacts aswell.

So my question is: Is there any other way to manipulate the display name of an incoming call? (for the 3CX Windows Client)
I tried to do this through the Call Control API and Plugins for the 3CX Windows Client, but didn't found a working solution.
Any help would be appreciated.

I don't think what you want is doable since you don't want the PBX doing the lookups.

You would need to use a custom built SIP server that does live lookups from your CRM
when incoming calls arrive, and act as the trunk to 3CX.
