The problem is definitely withing pj_gethostname blocking in the c gethostname() function. I replaced the "pj_gethostname()->ptr" call at the end of pjsua_create() with just "TESTTESTTEST" and the situation resolved. The blocking call to gethostname is now being called on a background thread (that is next time pj_gethostname is called, outside of the pjsua_create() call) as once I've called pjsua_create() all the rest of the setup is handled on the background thread. This can be a killer for iOS as when the app is backgrounded you only get 30 seconds to run, take any more time than this and the OS till forcibly terminate the app. I've found as long as the main thread remains responsive (that is running its runloop) then any other background threads can be blocked with no ill effects.
