1. Hi this is [you name], I’m either away from my desk or on the phone, please leave your name and number along with a short message and I’ll be sure to get back to you.
The most professional approach would be to avoid using your personal cellphone, and go for a modern "business phone" solution. Luckily these days the options can be very diverse and inexpensive.

Timing is everything. The moment you receive the lead alert is the best time to make the follow-up call. If you call them days later, your chances of getting them on the phone are greatly diminished. By calling them right away, you’ll talk to more leads which will inevitably boosts sales. Role-play your voicemail scripts so you sound like you’re making your 20th call, not your 1st. Ask your friends and colleagues for honest feedback on your voicemail scripts. Continually review what’s working and what isn’t -- there’s always room for improvement. If you have the lead’s email address, follow up with an email, and let them know in the voicemail you’re going to do so. If you don’t have an email, let them know you’ll follow up with a text.
There you have it, a basic introduction into how to write the best voicemail greetings. As you have seen, they’re not as easy as you’d think, but once you get comfortable with the type of information required by each, writing and recording your own should be a piece of cake. If you’ve tried to write one yourself and still don’t ‘feel you’ve captured the right essence, then please look at one of our voicemails greeting templates. When it comes to recording it, remember to rehearse your script and speak clearly. If you don’t care for your own voice, then have someone else record it, or hire a professional voice actor. Remember, there are also free audio editing software programs like Audacity, where you can manipulate your recording until you get exactly what you want.
