BSNL launches Voice over WiFi (VoWiFi):
BSNL has launched Voice over WiFi (VoWiFi) services nationwide across all telecom circles, enabling calls and messages over Wi-Fi.Voice over WiFi (VoWiFi) is a technology that allows users to make and receive voice calls and SMS over a Wi-Fi network instead of a mobile tower.
- It works using IMS (IP Multimedia Subsystem) and uses the same mobile number and phone dialer, without any third-party app.
- The smartphone uses an available home, office, or public Wi-Fi network to connect to the telecom network, instead of relying on a nearby mobile tower
- The user is authenticated through the SIM card, ensuring the same level of security and identity verification as regular mobile calls.
- Voice is converted into digital data packets and transmitted over the internet, allowing calls even where mobile signals cannot reach.
- When Wi-Fi becomes weak or unavailable, the call automatically shifts to the mobile network (VoLTE) without interruption or call drop.
