With the increasing number of businesses engaged in fraudulent activity and personal identity theft, it is no wonder why people are too concerned about who they are dealing business with. There are a lot of things that you can possible do in order to project the perfect image your company needs. From having a professionally looking website up to an appealing office in a great location, the companies that consider growing the client base seriously will do anything they can. But there’s one thing they often miss or really don’t consider: A professionally sounding voicemail greeting.
You could also record a custom greeting in a visual voicemail app, if you have one installed.

You don’t want to answer calls 24/7 (unless you’re serving clients globally and there’s an expectation of 24/7 support). If you’re unavailable during specific hours of the day, use the voicemail examples below for after-hours business calls.
On the iPhone, go into voicemail and tap "Greeting". Record a few seconds of something and tap stop. Before you tap save, use iFuntastic or SFTP to navigate to /var/root/Library/Voicemail on your iPhone. You'll see a file called "Greeting. amr". This is the audio you just recorded. Delete that file and replace it with your custom message which should then be renamed to "Greeting.amr". Tap "Play" on the iPhone to verify your message works. If it plays, tap "Save" and your custom message will be uploaded to AT&T's servers.
