[sip-comm-dev] Throwing NULL while Registering with SIP Account


Hi Team
          I'm using SIP Communicator for Automation purpose and I'm starting the client using windows command and also closing with the same. Last few days I'm facing an issue in SIP Communicator.
          Actually i can't able to register with the client once i closed the client for more than 3 times. (I Registered with SIP Account). That time it will throws a null value. The code which i used to kill the client is given below. And i have attached the screen shot too.
            Runtime r = Runtime.getRuntime();
            Process process = r.exec("cmd /c \"start /B taskkill.exe /F /IM run.exe /T\"");

Can you please give me the solution to solve this issue ?

Thanks & Regards
