> Party A calls Party B (and call is answered).
> Party B puts Party A on hold and blind transfers to Party C.
> Asterisk sends a SIP NOTIFY with a sipfrag 200 OK (after various NOTIFY with 1xx progress sipfrags) before the transferred call (to Party C) has been answered.
> The expected behaviour is for the all the NOTIFYs to be sent with sipfrags reflecting the upstream progress of the transferred call.
