Avoid beeps and radio silence. Once a customer has been placed on hold on radio silence, the customer tends to hang up in less than 40 seconds because that customer thinks, "I've been forgotten".
"Congratulations on Best of Show! I was in charge of the [Fifth District ADDY Awards] judging and was there when we played your On Hold Messaging. Very creative. I remember the judges commenting that it was a great use of an underutilized medium. Funny (and effective) stuff. Also goes to show that you don't need to go to the big city to get great creative work." - John McCafferty / McCafferty and Company Advertising

Highly recommend, Excellent company, headset ordered arrived in great time, absolutely fantastic customer service from Jo and excellent technical advice from Scott. Keep up the good work
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.
