I haven't used this device for an extended period, but since there are no mechanical parts, I expect that it will last. We have been using a professional on hold service for many years at about $60/month. The box that the professional company gave us sounded great when customers would call from a Lan Line. But, when calling from cell phone the voice messages were lower volume and the music would sound horrible. Music keeps cutting in and out and sounds very staticky. So we decided to save some $ and cancel our subscription and buy this unit. We are using the default music and voice messages that came preloaded instead of doing our own music and messages.
Can I use the music of my favorite artist/band/performer as the background to my Message on Hold program?

Combine with a Business Intro Message to provide menu options and assist in telephone navigation. As opposed to the passive nature of Messages On Hold, voice prompts are interactive. They are designed to bring out a physical reaction from the caller, a call to action. And because voice prompts are directive, it’s important they’re concise, well written, and recorded by a professional voice artist.
This plays immediately after the initial greeting message. If all agents continue to remain busy, the caller will continue to hear the On Hold Music, which can be either music or a message. Click Create Call Queue or click Edit (pencil icon) to the right of the queue you wish to select. Select Change under Hold Music. Enter the Name and the Phone Number or Extension you wish to record your initial greeting on. Click Call Now and follow the instructions.
