The 501 is more "weird" then that. The cat5 cable with the built in

need a "special" cable (the pairs are just different you can probably
look it up and make your own).
Is this true? I read earlier on the list that there's some sort of logic
unit in the cable -- but if it's just a matter of pin assignments, I'll
make my own effing cable ;)
Does anybody have a clear answer on this?
The IP 501 supports both Cisco and 802.11af with different cables. While
there are pin assignments differences, there are also electrical
differences in the discovery protocols. The special cable is an artifact
of this.
I don't know of anyone who was able to make the phone work without the
cable, and the 501 is not designed to work without it. If it were just a
matter of pin assignments, then people would be selling cables on eBay.
I notice that now that 802.11af is THE standard, Polycom is supporting
it on their new phones without any special cables.
