How IP hard phones powered (in the config tested and in the system pricing)	802.3af-compliant power hubs made by PowerDsine	Avaya P333 L2 switch and by in-line power-insertion unit	802.3af-compliant power hubs made by PowerDsine	Individual-phone, AC plug-in power-supply adapters
Additional, standalone application server(s) in the configuration tested	2 x Win2000; one for OmniVista server, and one for soft-phone administration	3 x Win2000: one for Avaya Site Admin (ASA); one for network and VoIP monitoring; and one for call accounting	3 x Win2000: one for Manage E & I appl’ns and fault manager; one for Traffic Analysis (TA); and one for email & unified messaging	None; requires just Java (JRE 1.3.1-based) Web browser access

(1) Per-phone and system prices are based on: the same model call controller(s) used in the testing; voicemail and directory; half IP soft-phone stations and half IP hard phones; T1 trunks; and all of the management applications used in the evaluation. The IP hard phones are mid-range models: All support an extra switch port, at least 10 buttons and a LCD display. See exceptions for Vertical below (3).
(2) In the Avaya configuration tested and in the systems priced, half of the IP hard phones are powered by Avaya P333 L2 switches, and in-line power-insertion units power half. Both are 802.3af-compliant.
(3) Vertical does not now support a soft phone. So in lieu of soft phones in the pricing, $100 analog phones were used to approximate a typical per-soft-phone-license cost. Vertical also does not support an integral user directory, as do the other systems tested, and currently supports just one IP hard-phone model, which customers acquire directly from Polycom.
