Hi Benny, ? I downloaded the latest pjsip. I was able to build the project in release mode but when the sample pjsua app received or create a call, I got an error ? Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. ? If I build the project in debug mode there are 3 errors. ? I tried creating my own project and it runs perfectly in debug mode but when I tried to run on release it resulted in the same error above ? Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. ? Please help. ?
