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.

It’s important to ensure the content is informative and relevant to the caller. And the rule ‘less is more’ very much applies to writing for the ear. It’s important to keep the sentences short and to the point. A popular way to get a message across is follow this structure: Introduce the topic in the first sentence e.g. Did you know that BusinessCo now offers no contract plans for hosted PBX and business VoIP? Explain how the information will benefit the caller in the second sentence e.g. And that means complete flexibility for your business and no long-term commitments. Wrap up with a call to action in the third sentence e.g. To find out more, visit our website businesspbx.com.au or speak to one of our Business Consultants when you come off hold.
