Australian mobile network operator (MNO) Optus has announced the launch of native voice-over-Wi-Fi (VoWi-Fi), or ‘WiFi Calling’ as it is branding it. Optus says that the service differs from its existing ‘WiFi Talk’ service, which is an app-based solution, and confirmed that its new offering is supported by inbuilt device technology and is set up on voice-over-LTE (VoLTE) enabled devices. In a press release it was confirmed that the Samsung Galaxy S7 and Galaxy S7 Edge are the first two devices to support WiFi Calling, though it was noted that plans are underway to introduce additional compatible handsets. In terms of coverage, Optus claims that WiFi Calling is available to subscribers across the country ‘wherever there is an accessible Wi-Fi service’.
Commenting on the launch, Dennis Wong, acting Managing Director, Optus Networks said: ‘When WiFi Calling is switched on, the device automatically detects and seamlessly switches to an available Wi-Fi connection to use voice and messaging services … Optus will continue to add other devices and expand the availability of WiFi Calling to more customers.’
