Yep it's exactly that.
The ims service works but I need to understand all and it's very complicated ^^
Code:
09-24 13:51:51.845: D/CII(2095): IMSEventListenerForNetwork: onSignalStrengthsChanged : SignalStrength: 8 2097251 -8 -200 -8 -200 -1 97 -97 -10 -199 0 2147483647 gsm|lte
09-24 13:51:51.845: D/CII(2095): IMSBaseFactory: getComponent with name : class com.sec.internal.ims.volte.imssystem.IMSExecutionManager
09-24 13:51:51.845: D/CII(2095): IMSExecutionManager: checkAvailability : true
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
