VoIP client in a browser?

Question

Google just announced that they will add support for VoIP calls in its Gmail application.

Does someone know how this will work? Did they manage to write a web-based VoIP client, or will they require the user to have Google Talk installed and somehow (how?) call this app from the browser?

I'd also like to provide customers with a way to make/receive calls through their browser, so that they wouldn't have to install an SIP client.

Thank you.

Answer 1

I've just noticed that in my inbox. They ask you to accept their EULA to start installing Google Voice. So it's not really a browser solution.

Answer 2

Google don't use a VoIP client in a browser. Instead the browser is used to initiate a callback to a phone number you must have previously registered. Once you answer that call Google Voice will then ring the destination number you specified and then bridge the calls together.
