Yet another missed opportunity for Google who purchased Grandcentral all those years ago. They already have call metrics for android devices. They could have had it for all the folks who would have dropped their PSTN lines for a Google Voice appliance as well as call history for anyone they called. Thought they wanted that kind of information but apparently not that much. Must be low value relative to web searches?

Would love to see a hack for Google home / Amazon echo that just turns them into dumb SIP devices. :-)
