As a professional business, in no way should you ever resort to leaving one of those generic, pre-recorded, “No one is here to take your call” messages that the phone company often provides. Record a greeting yourself, or have one professionally done for you. If you choose to record a greeting yourself for your office phone, there are a few simple keys that you should keep in mind:
People have short attention spans these days, and you should always craft your communications for the lowest common denominator with something as universal as your voicemail.

Many businesses want to sound professional and, as a result, end up creating boring, monotonous, and overly generic messages such as: “Hi, this is Joe. I’m either on the phone or away from my desk. Please leave me a message.”
Solution: Poor sound quality is unlikely the fault of a reliable business voicemail service that uses VoIP technology, Baldwin says. So garbled voicemails are often due to callers’ poor mobile phone reception while leaving their message—and you may just need to call them back, assuming you can figure out their phone number. But if the problem does seem to be your voicemail, make sure you’re using a business phone and voicemail service that uses VoIP and not relying on, say, your mobile phone’s voice mailbox.
