The team at Messages On Hold have been nothing but an absolute pleasure to deal with. Having dealt with several different departments to date, each interaction has been professional, friendly, prompt, informative and helpful. They've also displayed patience and understanding when there was some initial frustration with our beginning set up. We've had a fantastic experience and if you're looking for someone to look after your audio productions I can highly recommend their services.
Aren’t these on hold messages a lot better than being left in silence or just listening to the radio? Rather than being frustrated about waiting you’re being told exactly what you need to know. This saves both the caller and the business time all while increasing the likelihood of a successful deal.

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.
That’s a big piece of a trillion dollar pie! The good news is, you don’t have to let all these callers off the hook. Studies show that with creative, professional sounding on hold messages your business will retain customers holding on the line (in fact callers will wait up to 3 times longer than silence or music), but you can also generate revenue by marketing additional products and services.
