Hello, According to iPhone Application Programming Guide document,
In order for your application to maintain a persistent connection while it is in the background, you must configure the sockets used to communicate with your VoIP service. In iPhone OS, most sockets are managed using higher-level constructs such as streams. As a result, configuration of a socket to support VoIP occurs through the higher-level interfaces. The only thing you have to do beyond the normal configuration is add a special key that tags the interface as being used for a VoIP service. I have another question, what can I do for VOIP app with socket implementation uses BSD udp sockets to support iOS backgrounding? I am confused, I don't know where to start. I have a voip app that uses pjsip. Any advice and help are very appreciated! :) Regards, Angie _________________________________________________________________ Hotmail: Powerful Free email with security by Microsoft. https://signup.live.com/signup.aspx?id=60969_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
