European communications service provider Tele2 is getting ready to offer VoLTE services to its 4G customers in Sweden, with the operator's group chief technology and information officer keen to make the most of the "amazing quality" capabilities of Single Radio Voice Call Continuity (SRVCC).

Speaking at the Huawei Global Mobile Broadband Forum in London this week, Joachim Horn said the service had been tested, and the supporting technology was now "in implementation… We're aiming to launch in 2014. The service has amazing quality -- I have experienced that at SK Telecom in South Korea." (See: 4G Finally Gets a Voice.)

Tele2 AB (Nasdaq: TLTO) isn't just launching VoLTE in Sweden: The operator is launching a 4G LTE-only service in The Netherlands that will "have VoLTE from day 1" based on an IMS platform from Mavenir.

The next big challenge, though, is to get the handsets users will demand. Horn admitted it might be 2015 before there is a decent volume of smartphones with native VoLTE support.
