Ok, I was able to fix this by adding a local account for the transports: pjsua_acc_add_local(TCPTransport, PJ_TRUE, NULL); Now I just got to make it work perfectly and then I'll be done. I don't know why none was helping me with figuring this out, I'm adding Chris Foba to this just incase this can help him out. Tips for backgrounding: 1. Add a local account for both TCP and UDP. 2. Have the registrar with ";transport=tcp" at the end for the first try of adding an account, and then don't have it for the second try just incase the server only supports UDP. 3. Have a interval of 600 seconds for the background handler to keep the application registered with the server. 4. Have both voip and audio in the plist so you can background the call.
