Google Home just added VOIP. It's pretty awesome. Doesn't need to connect to my phone or anything. I just said Ok Google, call mom cell and bam! Connected my Apple contacts to my Google contacts and voila
edit: wtf it also just added bluetooth?!
The one caveat is that it displays your numbers as "UNKNOWN NUMBER" when it should use your Google Voice #, at least when I tried one time
I'm interested in the Mini, but cant tell if it will have a speaker or need to be connected to one like a Dot
