1. Business voicemail greeting samples. If you have a main business phone number that’s shared with the customers or publicly listed, you’ll want to make sure it has a professional voicemail message to greet callers.

Obviously, prospects aren't going to listen to an overly long voicemail from a caller whose number they don't recognize, so pushing past 30 seconds ensures the message will get deleted almost immediately. On the other hand, buyers are also unlikely to listen to an overly short message.
Why not shorter than 20 seconds? The voicemail indicator will tell the contact how long the message is, and if it’s just 5 or 10 seconds, it may seem like a spam call or a wrong number, which means they won’t listen to it at all. Messages between 20 and 30 seconds seem important enough to listen to but not so long that they’re off-putting for the contact.
