With 4.5 SFOS released, I wonder what is the state with VoLTE support. Sounds like Jolla’s implementation is closed source. Any plans to release it? Earlier, we were told that it is too early and no definite answer could be given. Maybe it is the time?
I believe unofficially ported devices could benefit from looking into Jolla’s approach. Right now, I personally, even have no idea where to start digging. And, in principle, time used for duplicating efforts is not very efficiently spent.
