The rumor is that inevitably we’re going to see Google Voice merged totally into Hangouts, and that is getting significantly closer to reality. You can now make phone calls by means of Hangouts specifically from the Google Voice website, no Google+ necessary. As Mountain View’s Alex Wiesen notes on G+, the new feature is recorded as an alternative in the “phone to call with” drop-down box. It appears a bit minor, beyond any doubt, particularly when you consider that Hangouts is the manner by which you make phone calls from inside Gmail, yet any redesign update for the oft- neglected service are welcome, right?
