Google Buying GrandCentral

Today I was reading on Techcrunch that Google is in acquisition discussions with telephone management startup GrandCentral they think that the deal has been actually been closed.
The basic idea around GrandCentral is “one phone number for all your phones, for life.” As we change jobs, homes and cell phones, there are a lot of phone numbers to keep track of, and keeping everyone up to date with your most recent phone numbers is a real cost. If you use GrandCentral you can give out a single phone number. What happens when that person calls that number depends on his/her relationship to you, and what you are doing at the time.The company, which has raised less than $6 million in capital from Minor Ventures lauched on September and is still in Beta.Also it available only for US and Canada for now.
