Insurance agents have to deal with large numbers of clients almost all through the year. So, they are extremely busy and cannot take calls of clients. For them resorting to voicemail messages become inevitable. Here is one instance of VOIP phone service for businesses like this:
A phone call to your business is often the first encounter your customers and prospects have with your company. If no one is available to take the call, having the best professional voicemail greetings possible is important to leave a great first impression and to ensure that business opportunities don’t slip by.

Avoid using ‘please’ more than once, it gets wordy and redundant. The goal is to keep the content as concise as possible, moving callers quickly and seamlessly through the options.
Your voicemail message should ideally answer all of the following requirements: Brief -- nothing bores callers as much (or makes them hang up as often) as long voicemail messages Informative -- if it's your professional voicemail, say your name, business, and if necessary, department.
