The adoption of Voice over LTE (VoLTE) has been slow around the globe. High costs and complex deployment are some challenges faced by mobile operators, regardless of the business benefits that VoLTE might offer to them and their customers. Moreover, for the carriers already operating 4G networks with VoLTE capacity, the number of devices with VoLTE or Wi-Fi calling support is limited, forcing operators to deal with costly 2G or 3G roaming agreements for voice services.
As a practical solution, mobile operators can use the Exomi Voice Over Data solution to extend their voice services to almost any data network and most existing handsets. This solution can be deployed alongside VoLTE or in non-VoLTE networks, and it supports all data connections: LTE, 3G, 2G, and Wi-Fi.
Exomi Voice Over Data consists of VoIP servers, an optional lightweight IMS system, and downloadable apps. This technology brings Voice over Data to 95% of mobile devices in the market (for Android 4.4 and iOS 10 and above), ensuring that mobile operators can increase their capacity and reachability with minimal investment.
Launching is fast and simple: after installing the app, subscribers can start making Voice over Data calls right away using their phone’s native dialer. Indeed, the Exomi app is fully integrated into the native calling interface, phonebook, and contacts. This ensures a seamless user experience and high-quality phone calls without the need to open the app for calling at all! The phone call will be placed as a Voice over Data call based on the business model defined by the operator and the user’s own preferences.
Carriers operating multiple networks (4G, 3G, and 2G) can ramp down their legacy networks by offering Voice over Data for devices without VoLTE support, reducing the capacity requirements for 2G and 3G networks.
