GrandCentral: Greetings - Personalize your voicemail greetings by caller or group

You can play a personalized voicemail greeting based on the individual or group settings you have for any person in your GrandCentral address book. To create new greetings, just go to the Settings tab and click on the Greetings link for groups or to the Contact Cards in your Address Book for individuals. You can also record greetings by calling your own GrandCentral number and following the voice prompts. Listen to and update your greetings as many times as you like.

Use greetings to:

Play different voicemail messages for business, friends, family, or other groups you create
Treat people as individuals with personally addressed voicemail, like "Hi John..."
Have fun: Leave a message for your boss or parents that you are too busy working when you are really out having a good time
Have fun: Make your buddies laugh their heads off over a crazy greeting without freaking out others (who will hear the standard greeting when they call)
