GrandCentral currently in beta stage is a web based “Voice Communications” platform that Google acquired last year is now opened for Bloggers. You can directly sign up for this service, just go to Blogger Invite page on GrandCentral and register your number. The service is currently for U.S. users only, or at least, you will need a U.S. phone number to activate it.
GrandCentral, the Google service centralizes all your phone numbers and adds new features on top of them, it’s the Free! service, at least for now. "GrandCentral provides an innovative web-based voice communications platform that helps you manage all your phones and phone numbers through one simple interface. You get a single phone number that forwards to all of your phones, giving you one number for life."
Bloggers can add a widget that allows readers to call them without knowing their phone numbers. Readers enter their phone numbers and GrandCentral makes the connection by calling both parties. "When you add GrandCentral's WebCall button to your blog, your readers can easily call your phone or leave voicemails without ever seeing your telephone number. You can screen calls, either accepting them or sending them to voicemail, and you can even block unwanted callers altogether."
You can receive voicemail notifications by email or SMS, access your voicemail from a mobile phone or from a computer and embed the messages into a site. It's almost like your phone numbers become a part of Gmail, a service that aggregates all the communication tools you use in a single easy-to-access place. GrandCentral is not yet a part of Gmail and it only works in the US, but the integration is inevitable.Google, GrandCentral, Beta, Voice Communicaton, Web Service, Web Services, Invite, Bloggers
