IMS: VoLTE, VoWiFi, ViLTE, RCS

The global standards Voice Over LTE (VoLTE), Voice Over Wi-Fi (VoWiFi), Video Over LTE (ViLTE), SMS/MMS over LTE, SMS/MMS over WiFi, and the Rich Communication Services (RCS) are based on the IP Multimedia Subsystem (IMS).

The IMS architectural framework enables mobile network technologies, such as 4G and 5G, to converge data and speech, offering high-quality voice or video calls over IP-based networks.

The Voice Over LTE (VoLTE) is vastly implemented by mobile operators globally, replacing the Circuit-Switched Fall-Back technology (CSFB), which falls back to a legacy 3G or 2G network when a voice or message service is requested by a user. As many mobile operators are switching-off their legacy network technologies, VoLTE is one of the solutions to continue offering voice service.

Additionally, Voice Over WiFi (VoWiFi), or as known as Wi-Fi Calling, is also a vastly implemented feature by mobile operators, requiring specific customization, icons, and some other important testing scenarios, such as the handover to/from VoLTE, and many other scenarios.

Our team handles the knowledge and experience of testing IMS, delivering a complete testing process from execution, narrowing down the failure scenarios, steps to reproduce, logs and evidence collection, deliver a complete report of the testing execution and detailed report.

Beyond the technical know-how, our team also helps your company with local requirements of customization and default settings of IMS services, through the experience of testing with different mobile operators globally.

TADTELMAX is ready to start testing IMS services, with the infrastructure required, and local presence in more than +50 countries.
