GrandCentral: Screening - Know who is calling and screen unknown callers

Whether you receive your call on a home, work or mobile phone, we'll tell you who's calling before you accept the call. If the number of the phone calling you is already in your GrandCentral address book, we'll let you know the name you have for that contact. If it is a new phone, GrandCentral can ask the person for their name the first time they call (after that we'll remember).

Use screening to:

Know who is calling before accepting
Avoid talking to people you aren't in the mood for
Have fun: Stop telemarketers in their tracks by never picking up, and then blocking their number so they don't call again

Tip: Import your contacts to make screening more effective in identfying the callers for you
