While missed calls aren’t ideal, you can let your caller know you’re still there for them by having a great voicemail greeting. The best business voicemail greetings let your customers (and potential customers) know why you’re not available and how they can best get in contact with your business. They are also short and to the point. You usually want to keep your greeting between 6 and 24 seconds long so callers don’t hang up halfway through.
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.

1. Set up voicemail. To set your voicemail box using the phone connected to your AT&T Voicemail (such as your home number), follow these steps: Dial *98 or dial your Access Number.
If you’re actively looking for a telecommuting gig, or you’re a small business owner looking to project a polished, professional image, do yourself a favor and call the number you’re giving out and listen to your voicemail greeting or, heaven forbid, see how your phone is answered by whatever family member happens to pick up the ringing phone. Are you impressed, or embarrassed? Was it useful, or was it a colossal waste of your time? Could you understand every word clearly, or did it sound like you were in a tent in the middle of a monsoon? Is the information you provided recent, or was it dreadfully out of date? Did it sound like someone you want to work with or hire? Or not?
