I have a confession to make: I haven’t recorded a new voicemail greeting since 2014. In the past four years, I (hopefully) have become more articulate, poised, and self-assured. But hear my voicemail recording, and you’d think I was still new to the work world, a little unsure of myself — and probably not an authority. Obviously I need toupdate it. And if you haven’t changed your voicemail greeting in over a year, you’re likely in the same boat. After all, a professional voicemail recording boosts your credibility, makes you seem more competent, and encourages whoever’s listening to it to continue the relationship. A relatively unprofessional one — like mine, for instance — does the opposite: It encourages prospects, recruiters, and potential connections to run in the other direction. With that in mind, I’ve written 18 unique voicemail greetings for every situation. Pick your favorite, practice a few times, then record your new voicemail.
3. Hello, this is [your name]. I’m sorry I’ve missed your call. If you leave your name, number, and reason for calling, I’ll get back to you as promptly as possible.

If you drone on and on, there is a good chance that some of your callers are going to hang up before leaving their message.
The easiest way to record and program professional voicemail greetings for your phone system is to write down a script. Choose someone to record your script - the one who can speak without hesitating or stuttering, has a friendly voice and can annunciate and pronounce each name and word clearly.
