I don't know if this is related, but I couldn't get my sipura spa-841
working using any of the half-dozen store-bought cat-5 patch cables I
had laying around.  It just refused to register.  Tcpdump confirmed
that packets were coming from it, and we answered, but it never
"heard" us.  Just out of randomness I tried the shorter enclosed cable
that came with the spa-841 and would you believe that it started
working?

As far as I can tell, the rj-45 socket on the phone is just a bit
non-standard and the wires just don't make reliable contact to the
spades on the cable.  It isn't a case of some of the wires in the
socket being bent, they are all straight and look "normal".  All I can
think is that the contact wires have a slightly higher than normal
angle and end up hitting the plastic lip of the rj-45 plug instead of
resting on the gold spade contacts.
