VoIP Switch - WhatsApp-Inspired VoIP Android App Awaaz Creates Ripples At Google Play

April 04, 2014


Recently, in an eyeball-grabbing $19 billion deal, Facebook (News - Alert) acquired the messaging app WhatsApp.  A price like this reminds us of the huge popularity of the free chatting app that apparently has taken the whole world under its tight grip. Under this backdrop it came as no surprise as a new, innovative WhatsApp- inspired mobile app makes it to Google (News - Alert) Play.

Anuj Jain, a tech-graduate from Delhi University and the creator of the app, aptly christened his creation as “Awaaz” the Hindi word for “sound.” While there is no dearth of applications that allow you make voice calls, only a few of them would allow you to do so for free.

By letting users make free calls to each other using their mobile phones, Awaaz aspires to fill the void. The VoIP (Voice over IP telephony) app enables the calls to be automatically routed to the Internet, making paid calls and roaming charges superfluous. No user sign-up, no delineation of personal information; just like WhatsApp, Awaaz uses your phone number to connect you to a contact which you want to call. Of course, the other user needs to have this app installed in his/her phone and be online.

The app has been designed to work more like a plug-in than an application. A user never needs to run the app except for the first time after installation or an upgrade, Jain explained in a statement.

There is no dialer within Awaaz to make a call.  A caller can use the regular phone dialer to make calls and the app automatically connects the call to the other user’s Android (News - Alert) phone.

Privacy and security of your calls are taken care of with enterprise-grade encryption using a 256-bit AES key exchanged using 2048-bit RSA (News - Alert). New keys are generated for every new call.

Within three months of its debut, the app reportedly has managed to garner more than 5,500 users in U.S., Europe and Australia. The maker of the app revealed his plan of releasing a premium, paid version in the upcoming months with new features like voice mail, conference calling and more.
