Google has no shortage of communication services and apps that overlap in any way. Some of them have shown no love, sometimes even for years. Google Voice may be the one with the shortest end of the stick, though it's useful. Now, however, Google seems to be preparing the biggest update to the service for a long time. It calls beta testers for its Wi-Fi and mobile data calls, including VoIP, which of course overlap with other Google apps and services that already offer the same functionality.
Google Voice has the advantage of only one number associated with your user, no matter how many devices you actually have. With some black magic (forwarding) it uses the same lines you use for normal voice calls. However, cellular voice calls are no longer fashionable today. Internet based are all the rave.
In some cases, the use of (sometimes free) Wi-Fi or even your LTE data plan could be the cheaper option. In these cases, Google Voice is pretty useless. There is evidence that Google builds the ability to do so. And this beta test is the first official confirmation that it will soon become a reality.
There will certainly be some confusion, especially if you already use Google's dizzying collection of communication tools and services. For example, while Google Voice works directly through the Android Phone Dialer or the Google Phone App, this new VoIP feature only needs to be used in the Google Voice app. Funnily, you can still get a VoIP call from Hangouts during a VoIP voice call from VoIP. So Google suggests disabling Hangouts if you want to test it.
While the application form is already available to help brave Google Voice users who still want to join, there's still no date on which the test will actually begin. And of course that means there's not enough time before the feature will actually be available to all Google Voice users. But at least it is now official and now only a matter of time.
