Found these guys super efficient and well priced. Our contacts Sarah and Jaity were very professional. Will definitely use them from here forward for our business.
AIM Dental Marketing® provides a complete turn-key package that works seamlessly with your existing phone system. Simply review our extensive library of dental on hold messages, then select up to 6 messages, adding any practice-specific information you would like. Our professional script writers review your input, and further customize the messages to your specifications. Once you approve your final message, our studio engineers create a customized recording for your exclusive use. We upload your approved audio file for easy download to your telephone system.

Solo guitar and piano music can also be decent choices provided you avoid songs with extremes of high and low volumes and pitch. Most phone systems come with default tracks that, coincidentally, fall squarely into these categories. If you’d like something a bit different then you can find plenty royalty-free tunes available to purchase online (they’re not all that terrible), but remember you'll need to pay for a PRS license if you want to make use of tracks by a recording artist.
VoIP providers also use other audio technologies such as silence suppression, background noise removal, echo cancellation, etc, which also affect the way voice sounds, and on hold music too.
