Maybe it's just me, but I've had this functionality on the iOS version of Hangouts for a while (I already have Google Voice). Outgoing phone calls from Hangouts show my GV number as caller ID. Incoming calls also ring on my Hangouts app. I did not know that that wasn't available for Android users...
Anyway, it's very handy. I have a US Google Voice account, but live abroad. Calls from hangouts are the primary way I talk to my friends and family back home. Wifi or a very strong 4G signal is required, 3G doesn't really cut it.
Yeah, been using it for maybe half a year. Also have Google Voice — maybe that was a prerequisite?
Seconding Hangouts as a really great solution for travelers. Bonus tip: if you're going away for a while, transfer your cell number to Google Voice and avoid the mess of having everyone update your phone # in their contacts.
Not just you. I was traveling internationally the last few weeks and was using the phone calling in my iOS hangouts app the entire time! So, this announcement must be either slightly belated, or they've been testing it on iOS beforehand?
