Google Home voice calling starts rolling out today

Google Home is getting a big upgrade today: The smart speaker can now place voice calls, no cellphone needed. This feature was first announced back at Google I/O in May, but it's now ready to roll out to users in the US and Canada. It's yet another feature that helps keep the Home competitive with Amazon's Echo family, which added calling back in May. We haven't gotten to try it out yet, but it sounds like it should be pretty straightforward to get your Home working as a speakerphone. But there are a few things you'll want to know before you give it a shot.
