Audio Hi-Q on G.722 Calls

The Aastra IP phones support the Hi-Q (high quality) audio technology which delivers enhanced
performance and voice clarity for Aastra's 6700i series of SIP phones. Incorporating wideband
audio technology, Aastra Hi-Q significantly improves the audio quality of calls. This technology
provides a more lifelike conversation when the G.722 wideband Codec is used. The phones with
5-line LCD screens display a large icon when Hi-Q is being used on the call. On 3-line LCD
screens, the text of "Hi-Q" displays on the same line as the call timer.
