On the other hand, a stellar professional voicemail is more than just a way to ensure callers are heard. It’s actually a gateway to encourage recruiters, clients, connections, venders, and other callers to continue forward with the first step in developing a business relationship, which is them making contact. The power of the right voicemail greeting is the caller actually staying on the line to leave that contact information or gain access to an alternative contact point.
Most of you will agree when I say that one of the coolest features of Google+ is Circles, which lets you create groups of people to share specific things with, rather than sharing with everyone in your network by default. Today I came across an iOS app that basically has the same system in place, but for voicemail. It’s called On Voicefeed and it lets you build groups (family, friends, work, girlfriend/boyfriend) and set personalized voicemail greetings for each of those groups.

Set up Visual Voicemail. If your carrier supports Visual Voicemail, you can set it up with these steps: Go to the Phone app, then tap the Voicemail tab. Tap Set Up Now. Create a voicemail password, then tap Done. Enter your password again to confirm it, then tap Done. Select Custom or Default. If you choose Custom, you can record a new greeting.
While a short recording may not seem like a place to win new business, the professionalism, courtesy, and clearness that you convey in your greeting will leave a favorable impression in a customer's mind.
