</div></div>So go in one Saturday morning, wire it up as you want (BT -> Asterisk) and<br>
the re-configure all the SIP phones to talk directly to the asterisk box<br>
and not the swyx box, then arrange the the swyx box to misteriously die,<br>
then tell everyone what a good job it was that you were in on the weekend<br>
to re-configure the phones to use the asterisk box ;-)<br>
