Silicon Valley based RingCentral offers businesses a virtual telephone system (they say “Sound more professional, look like a bigger company”). It’s sort of a super-Vonage, but targeted to businesses first. And they have a lot more features, including a virtual PBX to manage multiple lines and “greetings recorded by professional voice talent.”
The company took $12 million in late 2007 from Sequoia Capital and Khosla Ventures. Today they announced a second round, also $12 million. The round was led by DAG Ventures, which often follows Sequoia and other well known venture capitalists in second, more expensive rounds.
