OnSIP’s enhanced music on hold allows each user to select their own hold music, so each caller gets different tunes depending on who put them on hold or which menu they came in through. (You can even change your hold music for the holidays or for a special event!) You can also record a customized hold message to engage your callers while they’re waiting on the line. This presents a great opportunity to advertise additional features of your business or inform your audience of a special sale or promotion.
After the “message before answering”, the waiting announcement is immediately cut. Hold messages scripts are very powerful for you to keep your callers interested and reduce the tendency of drop calls. Here are some additional samples of hold messages scripts you can use for your business: General Business - On Hold Example

Have you ever judged a company based on how poor their phone messages were? We have. Avoid giving your existing or potential customers negative arguments about the quality of your service or brand image.
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.
