Thanks for your response, Pai. I've tried running on iOS 5 and 6, iPads (1st/3rd gen), iPod Touches, iPhone 3GS, 4, 4S, and 5. All show the same results. I should point out that the TCP connection is closed when there is no active calls in place. (ie: lurking in the background waiting for a call to come in) If an active call is in place, the app never gets shutdown for the duration of a call as the call's background audio prevents the device from truly sleeping. With a 1m registration timeout that would force a device wake-up every minute and burn thru battery, would it not? cheers, - John On 2012-10-31 11:34 AM, Pai Peng wrote: > with which device/iOS/Pjsip have you tested? > > I have just tested with one iPhone 4 iOS6 and pjsip 2.0.
