A complex technology like VoLTE explained in a most simpler way!
The content on VoLTE is designed & stitched so well in the slide-pack that it will help in building the concept and will aid an individual in further deep diving on the subject based on his/her interest.
I personally found it very useful and recommend others to take benefit from this tutorial.
