Business voicemail greetings are rarely thought of as a prime way to connect with customers. But just because you're not available doesn't mean you can't make a positive impression on your customers when they reach your voicemail box.
Once you have your new iPhone in hand and you are learning how to use it, one of the first things you may want to do is record a voicemail greeting. You have the option of using a default one that tells the person what number they have called, but you may elect for a more personal option.

That way you'll get to know exactly what other people hear when they call your phone and one last thing I wanted to show you. If you don't see that play on record option on the bottom, you don't have visual voicemail. Set up on your phone and that's through your provider. So if you have at and T sprint T-Mobile or any other provider, you need to have visual voicemail.
Forget about messing around with apps. There’s a powerful voicemail handling system built into nearly every big carrier today — and that system almost always includes a system for recording a voice message and sending it directly without ringing the target phone. I will walk you through the process of doing this on Straight Talk (since that happens to be my carrier) but most carriers will have similar systems.
