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.
Every call placed to your business is a possible sales opportunity. Whether a caller holds for a few seconds, or a few minutes can make a big difference in the outcome of that opportunity. A customized, sales oriented message program from hpc will help you give your callers a reason to stay on the line.

That said, despite having the tools to get it done, you may still be wondering how to actually sit down and create on hold messages. At its essence, your script is the business’s framework and what sets the stage for how callers interact with you. The only other 2 alternatives are your front door (if you have one) and your website.
