If you still can’t find the right hold music or are lost among all the possibilities, you can create your own radio station that streams any music you’d like to your callers or upload your own MP3 files.
When it came to integration with our platform, these new Easy On Hold features were incorporated seamlessly. "In testing, I was quite surprised at how little time the whole set up process took and how efficiently the stream stood up to testing," said NOC Technician Eric Phipps. "It's very rare that we encounter a new product that integrates so quickly and hassle free in the testing phase."

24% said that on hold messaging had been directly responsible for sales (54% were unsure as they do not track this kind of information)
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.
