Do you experience the same problem if you start your phone in safe mode:

no phone call problem when i put the phone in safe mood,,so how a solution?
If it works fine when the phone is in safe mode there is a third party application that is causing the problem. I suggest you take a look at your downloaded applications to see if you can determine which app that is causing the problem.
Go to Settings > Apps > And you will end up on the tab "Downloaded".
thanks for your information now i will try uninstall the third party applicaton..
thanks for your consideration.. 
I would start uninstall apps that are phone call and microphone related to see if you notice any difference.
