For those still using analogue or digital phone systems, voice on ISDN circuits has a bandwidth of around 4000Hz. The audio from an analogue phone is sampled at 8000Hz, and because of the nyquist theorem, must be low-pass filtered to 4000Hz. So any frequencies in the audio beyond 4000Hz are lost. Interestingly, the human ear and mind are good at recognising human speech, so this is considered "toll-quality" voice, i.e. good enough to pay for. This is the reason why certain vocalised letters are difficult or impossible to tell apart on the phone. For example, the differences between B, P, T, C, etc. are almost entirely above 4000Hz.
The Business Audio Music On-Hold System (GDI-USBM10) is an on-hold audio player for use with any telephone system such as PBX's, IPBX's or Key Phone systems. The music on hold player is designed for ease of use. Simply plug the Grace Music and Messaging on Hold Player into your telephone systems' audio input jack (typically marked as ‘music on hold') via the included audio cable then insert the included USB thumb drive and the fully licensed music for businesses will automatically start playing.
