Make sure to remind your caller to leave their name, number and the details of why they are calling, so you can ring them back professionally and constructively.
Rehearse your greeting a few times before you press record. Plan your pauses and select natural places to take a breath. If you are recording directly into your phone don't hold it to your ear like you are talking on the phone. This can produce a muffled tone. Hold the phone out in front of you a few inches from your mouth for the clearest recording. This may require some trial and error. So playback your greeting and make necessary adjustments on your re-record.

A good voicemail greeting is short and professional, lets people know that you’ll get back to them, and invites callers to continue engaging with a call-to-action. You should also show your personality if you’re in an industry or role that allows that. If your industry is more conservative, however, you’ll want to keep humor and personal touches to a minimum.
