Using your cell phone to record a voicemail message isn't always easy. Between remembering what to say and getting the right timing, it's tricky. But your phone does have a playback option, and it's easy to listen to and review your message. For some people, though, cutting off the end of a message is a funny way to trick people and catch them off guard. In most situations, callers won't know it's intentional and will think you're far less than tech savvy. Definitely not an impression I'd want to make.
“Who is this on the telephone? Sorry but no one is at home. Gosh oh gee, but I have fun, taking down messages one by one. I’m an orphan but rich people are going to adopt me; they always do. So if you’re rich, leave a message and the studio will call you back.”

If your customers feel that you don’t care, they’ll take their business elsewhere. Experiences are the differentiating factor between businesses. Big efforts to improve the overall experience in tiny ways by crafting a voicemail greeting script can make a huge difference when customers are asked by their friends and family how easy it was to work with you. And word spreads quickly in the age of social media. The more positive experiences you offer, even when you’re not available, the more likely those people will call back.
However, unlike a traditional PBX, the service is hosted in the cloud. By setting up fail over actions for Auto Attendants, and groups you can make sure that calls will be delivered. You also have the options to setup Find-Me/Follow-Me or Call Forwarding for each user extension.
