Once a leg of a call has been established, it's pretty darn difficult to
annihilate that leg without dropping the call.  You might be able to do it
with purely PRIs, using cause codes to drop one call leg at a time, but it
doesn't solve the problem of how to get that next leg set up with your
provider.  You need to have the control at the point where a call leg is
dropped, which has to be the same location where the next call leg is
attempted.

This is the developer explanation.  If you were looking for a simple, 
"No, that can't be done", you should have asked the -Users list.
