There exist a relatively long list of HD (G.722) SIP enabled hardphones in the enterprise category (Polycom, snom, AudioCodes, Cisco, Avaya, Mitel, Aastra, and several others) and two in the consumer category with Gigaset and Panasonic. The latter get their HD functionality by way of the DECT Forum CAT-IQ cordless standard. Trial participants can use HD G.722 IP phones from any source, but the Nova Trial currently only offers support for configuring IP phones from Polycom, snom, and Gigaset. Softphone options are not supported by the Nova Trial at the present time.
Moore's Law like forces arising from the competition between the large number of companies producing SIP phones is producing dramatic reductions in the cost and increases in the capabilities of the devices. Mobile HD options should be available relatively soon. The incorporation of HD functionality does not add much if any cost to devices in the various categories. It should not take too long before all fixed and mobile phones support HD by default.
Check this page frequently as we will add support for additional HD devices as they become available and internal testing efforts are completed.
Trial participants can get their HD phones directly from the manufacturer or via a distributor. For example:
Gigaset ($87 USD) via Amazon - configuration instructions
Polycom ($140 USD) via VoIPSupply - configuration instructions
snom two device kit ($495 USD) via ABPTech - configuration instructions
