Even if your wait time is short, don’t discount the power of hold music. OnSIP’s average wait time averaged 18 seconds last month, which is just long enough for the caller to notice that the instrumental music is pleasant, with enough character to prevent boredom, before our team picks up. When that’s the last thought in your caller’s head before speaking with your business, it’s likely to be a more pleasant conversation than it might have been otherwise.
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.

Regrettably for my purpose, the software requires that you add a "message on hold", which makes perfect sense for this devices intended purpose, if not for my own use. But I worked around the problem by recording a second of silence and then adjusted the software the effectively play only my cheesy elevator music.
Brian & the team have been looking after our telephone systems for a few years now. Always an excellent service. Very knowledgable and at hand, should any problems arise.
