Snom Upgrades Wideband Voice

Snom has announced klarVOICE. No, it’s not Klingon, it’s a
wideband handset that can be adopted to snom VoIP phones.

Wideband or “HD” style codecs provide higher quality voice
calls than the stock wireline PSTN/POTS standard sampled across 8 kHz. The new klarVOICE handset works with the G.722
wideband codec and with a sampling rate double that of a standard VoIP call is
capable of offering an effective pass through rate of 50 to 7,000 Hz; so-called
“narrowband” VoIP calls come in at about 200 to 3,300 Hz.  

The klarVOICE handset requires $32.50 (suggested
retail price) and a snom 3xxx series VoIP phone using the company’s latest
firmware release. An entry-level snom
300 phone lists around $183, so adding wideband as an upgrade isn’t that much
of a stretch.

Snom’s move to support G.722 makes life more interesting in
the HD voice arena. Cisco and Polycom also support G.722 on the handset side
and Asterisk provides IP PBX support. Freeconferencecall.com supports wideband voice
through WYDE voice hardware developed by a “sister company.” Skype also
supports G.722, but you have to go through some contortions to have Skype talk
to something other than another Skype client.
