Overriding Original Number in Call Transfer

Hello 

I have Teams with Direct Routing setup. I understand that in a call transfer, the phone number from original caller will be preserved up until the call reach to final transferee. But I have a case that this original caller number must be replaced by the Teams user's DID who does the transfer. I already disabled the Forward History, switching settings on Forward PAI even playing with Caller ID policy but still the original caller number shows up. I got recommendation doing it on SBC level but I will try as much as possible not to touch the SBC unless I really have to. Can it be done on Teams side or is it really need to be done on SBC level?

Thank you in advance.
