Will be sense for install it when I am not interested in VoLTE?Yep it's exactly that.
The ims service works but I need to understand all and it's very complicated ^^
I will share a new build with the ims framework but it will be a full alpha test.
I don't know what options I need to enable in csc settings and in the cm14, I don't know if my modem firmware is compatible, I don't know if my carrier is compatible, I don't know how the cm14 use the ims framework, I need to verify if I have all components to get hd call, ... so it's very hard :x
