Bring Wi-Fi and LTE Calling to Android


Source: OpenSignal, August 2015

There are over 24,000 An­droid de­vi­ces in the mar­ket to­day and on­ly a small hand­ful of the new­est de­vi­ces of­fer an em­bed­ded Voice over Wi-Fi cli­ent. Mo­bile Net­work Oper­a­tors (MNO) have a tre­men­dous opp­or­tu­ni­ty to roll out new voice ser­vi­ces such as Wi-Fi and LTE Calling to their Android-based subscribers.

Sonus’ Wi-Fi and LTE Calling solutions provide a true native calling and dialing experience that will delight both you and your entire Android customer base.


Sonus has the right solution to rapidly deploy Wi-Fi Calling and LTE Calling for both Mobile Network Operators and Mobile Virtual Network Operators.

Sonus Mobile Client: The Sonus Mobile Client is a downloadable application for Android devices that enables a true native calling and messaging experience whether over 2G/3G, Wi-Fi, or LTE. Your subscriber’s Android experience is completely unchanged, regardless of handset manufacturer or model. The Sonus Mobile Client is compliant with mobile industry standards for Wi-Fi Calling and compatible with standard IMS infrastructures from nearly every leading mobile core network provider, including the Sonus Virtual Mobile Core.

Sonus Virtual Mobile Core (VMC): The Sonus VMC eliminates the need for complex IMS deployments by combining standard IMS functions into a single virtual software solution. It also supports the Sonus Mobile Client for Wi-Fi and LTE Calling, as well as other native clients provided by device manufacturers, such as those on the Apple iPhone 5c and later, and a few high-end Android phones. By deploying the Sonus VMC, operators can deploy Wi-Fi and LTE Calling plus VoLTE services at a fraction of the time and effort.
