Diabetes kills more Americans each year than breast cancer and AIDS combined. As the number one diabetes advocate in America, the American Diabetes Association needed an easier way to update their 5 main call centers across the United States. Our Internet-connected On-Hold system allows easy management and update of the important American Diabetes Association messages. Katie McCall provides the voice of reassurance. http://prosoundusa.com/wp-content/blogs.dir/27/files/07-01-09-AmeriGas-Charlottesville1.mp3
In response to PsychedelicWonders. Call hold/call wait is a network feature (while it is activated by the handset) as such any music would be supplied by your carrier, there should be some there but chances are it's some wonderfull elevator style stuff (I'm partial to Brahms myself 😉 ).

Working with Holdcom to keep your program up to date is easy. Just tell your Client Relations Representative and Script Consultant the information and they’ll revise your script. They can replicate your advertising from newspaper or television ads, follow your social media updates, and check your website.
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.
