You made sense to me, but you seem to have abbreviated some information
out. Also thank you for searching a bit first.

As an example of what you want to do, I was doing some testing of a
application of ours. Our phone traffic comes in on box A, an was dialed
to box B. We don't like to change the dialplan on box A, so I told box B
to redirect to my test workstation(box C), and IAX handed off the call
from box b to my workstation. As long as you are using IAX as the box to
box transfers, it should transfer if it can and get out of the way. It
shouldn't matter that the final part of the call is SIP since the
transfers are on the asterisk boxes.
