Early this week, Google voicemail app Google Voice underwent a major overhaul earlier this week and it now sports a cleaner, more responsive and intuitive user interface. The tech giant also unveiled plans integrate VoIP into the app.

Google and VoIP. The California-based tech giant announced that it is currently working on putting VoIP capabilities into its Voice app. Currently, the app only has features that allow it to make regular calls on a provider's network.

The aim is to make the app not just a full featured mobile network alternative but a replacement with people being able to make calls regardless of the device being used. This new ability will enable calls to go through on a Wi-Fi network in the event that cellular networks are down.

Google is looking into making Google Voice the primary app for making calls. Until then, users will have to make do with Google's Hangouts app to make VoIP calls. This could possibly mean Hangouts being phased out in the future.

The Voice app is currently only available in the United States and Canada. It was released back in 2009 and lets users make calls, send text messages, and receive voicemail using a unique phone number from the tech giant free of charge. Aside from the ability to make regular calls and send text messages, the app also allows users to transcribe voicemails into text as well as make international calls at lower rates.

9to5Google, a website focused on everything Google-related quoted the tech giant as saying, "The updated Google Voice app doesn't have VoIP features - it has the same features for making calls as the existing Google Voice app. Hangouts will ring by default in addition to any forwarding phones on your account, just as it did before. (Again, not a change with the new app.) We are working on VoIP integration."
