The idea of creating a custom on-hold message may sound daunting, but advancements in technology have made it a lot easier in the last few years. In its simplest form, all you need is an audio file. Before you start, check with your IT support team or phone system vendor to see if there are any special requirements you need to be aware of.

The problem, in my mind, is that every single one of these articles misses the point completely. Even if you implemented a call centre system that detected and automatically played someone’s all-time favourite music while they waited, a facility which is possibly not that far off, most music when played down the phone just sounds terrible. Butchering a song that someone actually likes is unlikely to improve the waiting experience.
The decision to update your on-hold message depends largely on the content you are sharing. If you are sharing content that includes short-term promotions, this information will need frequent updating so consumers are always aware of the status of any offers. However, if you’re only sharing general information about your standard products, your operating hours and location, then the decision to update the message can be more reliant on metrics.
