VoIP, or Voice Over IP, is becoming a very popular alternative to traditional phone lines. This type of service operates over the internet, allowing businesses to make calls without paying for a regular phone service. If you use VoIP, that is no reason to forego on hold messaging. In fact, many services are now VoIP compatible. This makes your low-cost phone option that much better, because you can still enjoy the same useful marketing service.
Mixes of Mozart and Beethoven’s classic symphonies are a great way to keep customers engaged as they wait to get on hold.

No matter which kind of company you call — big or small — their on-hold music usually sounds like it has been recorded in a tin can. You would think that with modern technology being able to clone sheep and fly humans around faster than the speed of sound, that a creating a business phone system with clear and crisp on-hold music would be easy. But as it turns out, it isn’t so straightforward.
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.
