A comedic on hold message script isn’t just some novelty you can invest in because you feel like it. It’s a way to distinguish your company and establish your brand, and it can help make your customers more eager to do business with you. It’s icing on the cake of your company; without it, it’s not really a cake at all.
It depends on your business industry, type of callers and marketing plan. Assuming that you take a profit driven approach to using your telephone on hold messages as a marketing tool, you will want to consider changing at a minimum of twice per year, however its best to be more proactive and update more often like quarterly or even monthly. Callers love something new and refreshing (don’t we all!), particularly those that frequently call back and are placed on hold! Why not inform them them of special promotions, new products, or customer service info – there’s always something more that can be said! Make the most of your telephone’s on hold messaging infrastructure. It is an effective way to win, retain, and sell your callers on hold.

So what can we do to avoid inflicting further musical misery on our own customers while they’re patiently sitting on hold? We could just go back to playing a ringing sound, or an intermittent beep just to let people know they’re still connected, but that would be awfully dull. The best compromise is relatively simple electronic music that doesn't have too much going on as the ideal choice for hold music as it requires far less refined sound quality to get a decent rendition down a telephone connection.
You will most likely run into the typical Stalingrad-esque repeating messages that state how important your call is to the business. It is only slightly less annoying to have some form of default music that plays on a loop, and gives you the virtual experience of being stuck in an elevator, listening to muzak ad infinitum.
