Can I record HD Voice?

HD Voice is high-definition audio over VoIP phone service.  All digital recorders record standard VoIP and HD Voice.  The benefit of HD Voice is noticeably better-quality sound which improves recordings.  While on the phone, agents don’t have to ask callers to repeat their words.  HD Voice also significantly improves word search and speech recognition accuracy along with improved phone system’s interactive voice response (IVR) performance and improved conference call productivity.  Normally, calls are transmitted on a frequency of 300 Hz to 3.4 kHz.  HD voice expands the frequency range to between 50 Hz on the low end and 7 KHz and up on the high end. Revcord supports G.722 adaptive multi-rate wide band for certain Cisco/Ploycom phones.
