It's basically a 4 port switch that you replace your wall jack with. I used
the NJ200, it allows you to set priority per port, although I think they are
discontinued now. In combination with a 3Com power over Ethernet injector, I
was able to expand a 24 port LAN to a 96 port LAN with a per-port cost of
$62 Cdn. And, 24 ports of those 96 are PoE, so I can plug my phones right in

3. Use 3CNJVOIP-CPOD POE --> 7960 POE/Data splitters for power and data connections to the phone.

Cisco 79xx series IP phones

up a lot of 7912's (simple one line phones, same as the 7905 but it has

Asterisk.
I would recommend not going directly to cisco, and just find a reseller
