Blind Transfers

We have a customer scenario where users of a ring group are located geographically throughout the US. They are all on an inbound ring group. The issue users are having is that they cannot tell if a call from that ring group has been blind transferred to them or is a new inbound call.

Is there a way to prefix blind transfers so that users know the call is for them and the can still see who is calling without having to do an attended transfer?

Dialplan. Manipulate the caller id name (or number) field.
