Keep it Brief. Time is money in business, so if your voicemail is long, chances are the caller will simply disengage before the cue to leave a message even sounds. Keep your voicemail short. The most should be around 30 seconds, and even that’s pressing it. We’ve grown into a country where our attention span can last only about 10 seconds in some cases, so keep it short, brief and to the point. Persuade and Engage the Caller. If someone calls your business, they already have an intention. It’s the quality of your voicemail that plays a factor if they consider you a company they’d like to deal with. This is your chance to motivate someone to engage in a meaningful conversation with you. If your voicemail is shoddy, chances are they’ll hang up, or lose motivation to continue the call. In other words, your voice mail must engage and entice someone to the point that they care enough to leave you a message.
Follow these steps to record your name and greeting, and to select which greeting you want callers to hear.

Funny voicemail greetings are just that. These types of greetings have no rules whatsoever. They’re just for funsies, so make those you care for the laugh. Most of the time, they are personal, but certain businesses can use them as well. Perhaps you operate a theatrical costume company that specializes in clown memorabilia, or perhaps you run a business that sells pranks, such as plastic puppy poo, and whoopee cushions.
Leaving a voicemail can still be a good way to grab the attention of a potential new customer. However, when it comes to leaving a voicemail, you only have a few seconds to actually grab the listener's attention. Most salespeople screw this up by leaving too much information and making themselves sound like a salesperson, which is the kiss of death when leaving a voicemail.
