snom Introduces Wideband Voice Handset
snom technology AG, a manufacturer of VoIP phones for the commercial and residential markets, introduced a new handset, snom klarVOICE. This wideband handset, which can be adapted to all snom VoIP telephones, allows the capture of more than twice the spectrum of voice frequencies captured by standard phones, snom said.
The snom klarVOICE handset works with the codec G.722.2 PSTN. This codec is able to shrink the bit rate of the voice channel down to 12.65kbps. In standard narrowband VoIP calls, the voice signal is sampled at 8,000Hz, resulting in an effective voice pass-band of about 200Hz to 3,300Hz. The new wideband handset offers a doubled sample rate, providing an effective pass-band of 50Hz to 7,000Hz.
