A Reddit user spotted the change when initiating the call recently. so, launched a help page that outlines how the upgrade works, including the caveat that connections will reveal your Iaddress.  A representative confirmed to Venturebeat that will roll out the change across all platforms: Android, iOS, the web. So you may see such an improvement next time you use Hangouts to make a voice call. y this matters: This move should help Hangouts with better call quality, which I’ve found to often be a subpar frustrating experience. notes this feature will kick in when possible, so don’t expect to see it every single time.
