SingTel is preparing to launch voice over LTE (VoLTE) services in Singapore in the coming months.
The deployment, which uses Ericsson's VoLTE solution, enables calls to be connected in less than two seconds compared with five to ten seconds on 3G networks.
SingTel's VoLTE service will be the first of its kind to be equipped with Single Radio Voice Call Continuity (SRVCC) capability, whicg automatically switches ongoing calls without interruption to the 3G network if users lose connection to the 4G network.
