VoLTE support for nRF9160, is it available or will it be available?

Exactly as the subject states, we are in the progress to start development on a portable device communicating over LTE-M (CAT-M1) and we are in need of voice communication.
We are hoping that the nRF9160 module will support VoLTE, otherwise we will have to go for a more boring approach and use a 2G module for our product.

We're thankful if anyone has any information if the nRF9160 supports VoLTE?

Best regards
