Hi, I have using PJSIP 1.14.2 and iOS version 6.1.2. I am setting a Register expire time to 90 seconds for frequent presence update. PJSIP works fine in foreground mode over iOS and sends re-register at every 90 seconds but as soon as application moves to background PJSIP stops sending register messages. I have defined voip and audio modes in UIBackgroundModes in plist file and i am running PJSIP over TCP. Can anyone help me why this problem is occurring? Regards, Anuj
