IP Phones
IP Phones covers desk phones for VoIP systems: Avaya 9611G and 9641GS phones with color displays, Polycom VVX 301 and 311 six-line phones, and 3Com 3102 business phones for older VCX systems. Most run on PoE from the network switch. The phone has to support the call platform's signaling protocol, and sometimes its firmware, which matters more than the hardware features.

Buying guide
Matching phones to your phone system
Protocol
Polycom VVX phones are SIP phones; Avaya 96x1 phones run H.323 or SIP depending on the firmware loaded. Match what your call server expects.
Power
Most IP phones draw power from an 802.3af PoE switch port. Without PoE, you'll need a power supply or injector for each phone.
Gigabit pass-through
Models with gigabit ports, like the 9641GS, let a PC share the phone's network drop without slowing it to 100Mb.

Frequently asked questions
Will an Avaya 9611G work with a non-Avaya phone system?
With SIP firmware loaded it can register to some third-party SIP systems, but feature support varies. It's most at home on Avaya call servers.
Do IP phones need a PoE switch?
Not necessarily, but it's the usual setup. Without PoE, each phone needs its own power supply or a PoE injector.
