GrandCentral: receive calls and post voicemail with your blog
February 22, 2008
With GrandCentral, a free service from Google, you can receive phone calls and post voicemails right on your blog. Though GrandCentral is currently in a private beta test, bloggers can skip the wait and get a free account immediately.

WebCall Button
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.

Voicemail Inbox
Your voicemail is all kept in a visual online inbox that is easy to manage. Store as many as you like for as long as you like, or post them to your blog so anyone can hear them.
