Optus has launched voice-over-LTE, following Telstra and Vodafone's lead last year.
Voice-over-LTE, or VoLTE, is technology that integrates voice calls into the 4G data stream rather than have the network switch down to 3G for such purposes.
“VoLTE provides customers a number of benefits including high definition quality voice calls, faster call connections and the ability for customers to multitask on their device while browsing and making a call over a 4G connection,” said Optus networks managing director Dennis Wong.
The service will be available initially on Samsung Galaxy S7 and Galaxy S7 Edge, with progressive rollout to other devices. Geographically, Sydney, Melbourne, Brisbane, Adelaide, Perth and Canberra metropolitan areas will be the first to benefit.
Wong said that regional locations would be added to the VoLTE coverage area in time.
“We’ve all been on a call when we’ve needed to quickly look up the address of a restaurant or download a file from an email. With VoLTE, this will all be a lot faster and easier because you’ll stay on a 4G connection,” Wong said.
