[Xposed Framework Modules] yairh:
It seems you are using a custom built Xposed version:

01-14 14:00:27.586 I/Xposed ( 2529): Starting Xposed version 79.0 (custom build by wanam / 20151217), compiled for SDK 22

It also seems that there was an error while hooking the methods Callnect hooks:

01-14 14:00:28.636 I/Xposed ( 2529): Loading modules from /data/app/com.yairh.callnect-1/base.apk
01-14 14:00:28.716 E/Xposed ( 2529): java.lang.NoSuchMethodError: com.android.org.conscrypt.OpenSSLProvider#restoreUnsupportedServices()#bestmatch

01-14 14:00:28.716 E/Xposed ( 2529):	at de.robv.android.xposed.SamsungHelper$2.afterHookedMethod(SamsungHelper.java:86)

Take note of the last line of the quote here.

There is a function that is called whenever Xposed hooks a method, and it fails to load Callnect.

This function was written by wanam (SamsungHelper.java: https://github.com/wanam/XposedBridge/blob/art/src/de/robv/android/xposed/SamsungHelper.java).

My conclusion: The custom build of your Xposed doesn't play along with Callnect, and you should submit this issue to wanam's thread (link at the top of my reply) with the following traceback:
