We don't offer a free on hold demo. We simply provide a professional one-off audio production for a fair one-time fee.
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.

83% of callers who are put into a queue without custom on-hold features will hang up after just 15 seconds. 36% of these people will never call back again. With Custom hold messaging you can reduce hang-up rates for your business and engage callers while they wait.
Where this creates an extra snag with music on hold is that the loudest part of a song doesn’t typically come in until the final chorus or reprise. This means that if you just listen to the first 10 seconds to check that your new hold music is working, then chances are you’ll be blissfully unaware that three minutes into holding (just as customers are beginning to feel irritated anyway), you start playing a sound like fingernails on a blackboard to them.
