Unfortunately, it gets worse. Due to general sloppiness when it comes to setting the volume level for music on hold, a form of distortion known as “clipping” can appear, and regularly does if you’re willing to believe personal anecdotal evidence. If you want to know about the science behind clipping, then Wikipedia will tell you everything you need to know, but for those of us who have things to get on with, we can get by just knowing that when something is played too loud down a phone line, the sound starts to distort and sound really horrible.
All our customer service advisers are busy. Due to currrent high volume of calls, it may be some time before an adviser is able to take your call. either continue to hold or press 1 and leave your details and we will call you back later today.

If it is a genre, hold music, it's fair to say, is a troubled one with few hits. It's not really meant to be loved or even listened to — it's meant to communicate something specific: Don't hang up. (Cornell makes this plea specifically at the end of his song.) Silence is believed to be a death knell for phone calls — people will simply think the line is dead and hang up. This is true even on non-hold calls; it's why phone companies transmit something called a "comfort tone" over phone lines, a barely audible synthetic noise that signals a connection is still there.
Each recording is customised to suit your business requirements. You can choose from a range of tones, voice artists, or create a custom script for your on hold message.
