Telstra also said it will deploy Voice over LTE (VoLTE) across the 4G network by April, with a full commercial launch later in the year. VoLTE provides faster call connections on compatible mobile phones.
"Following successful network trials of VoLTE and [Video calling over LTE (ViLTE)] during 2014 and the implementation of Single Radio Voice Call Continuity, customers will soon be able to make a call using our 4G network layer and when needed, seamlessly transition from the 4G to 3G layer of the network with no interruption and retain the same level of call quality they experience now," said Wright.
"Once we have introduced VoLTE across the network, we will also expand testing to quality controlled video calling (ViLTE) and also [Voice over Wi-Fi (VoWiFi)]," said Mr Wright.
Vodafone announced last month it had completed its own trial of 4G VoLTE voice calls.
