Hello, I am unable to receive the call when the application ( downloaded from release tar ball, version 2.2.1 ) is in the background. I am using iOS7. But as soon as I open the application, showNotification method ( from ipjsuaAppDeletate gets executed ). However, it doesn't show anything ( as soon as I understand mainly because UILocalNotification should be alerted when the app is in the background, but once again showNotification isn't called, when it's in the background. ) I tried to delete all default account and add one with transport=TCP, but doesn't help. I've read the getting started guide, and found: Make sure that the TCP socket is successfully wrapped with CFReadStreamRef (check if there is a message: "Failed to configure TCP transport for VoIP usage") I don't see any "Failed to configure TCP transport for VoIP usage" in the Xcode console and I don't know how to wrap the TCP socket to CFReadStreamRef. Maybe you can provide me with some specific example?? ( like the file name and the line number, where I should do this ). Maybe there are some other suggestions? Any help will be highly appreciated! Thank you in advance
