I am using <pjsua-lib/pjsua.h> to interface with PJSIP in my APP and so far I am getting what I need from PJSIP.. I started to look at the background mode and I am a lil bit confused, I was able to code my own socket and make sure it is running what the APP is in the background but with PJSIP I think I am missing something: - We compile PJSIP for IOS and we get header files and libraries that we will use in xcode so how can I access the socket code and wrap it with what apple requires. - I read the getting started track and I am not what it means by ? Make sure TCP socket is wrapped with CFReadStreamRef? - Is the process simply just add UIBackgroundMode flag. I will be very thankful is someone can explain and shed more light into this process..
