Hello there fellow coders, I have installed and tested the pjsua on i{hone simulator. I tried making and receiving a few calls, and all worked fine. But now I want to understand the internal working of the UA. My query is : Where does the flow go from : textFieldShouldReturn delegate to the console_app_main where the keystorke is mapped to the functions, like m i for makeCall.
