Yes sets need to be plugged in for Call Forward to work.
I think the CP/CCR/Paths/Trsfer/Ext would be the best way to do it....means going full AA though.

I do wonder if BCM's MeetMe FollowMe would work in this scenario, will test if I have time.

As for "Transfer" on the older beasts you might notice the Conf/Trans key lables.....that is because on DR1 you must do a conference to do the transfer.
Receive call, Feature 3 (or press Conf/Trans), call 2nd person, drop out when connected.
