Hi all, I am using PJSIP library in my iOS application, and I could see that whenever the messages and send to the application its getting delivered if the application in in foreground. But in the case of background mode I could see that the messages are not getting delivered in some iOS devices. In my case I am getting messages in iPhone 4s,5s etc but not receiving the messages in iPhone 6, 6 plus etc, in those devices the message call back method on_pager are getting triggered when the application come to foreground. Any help on this issue is appreciated. *Thanks & Regards* *Kannan Prasad*

Any info on this is highly appreciated.... *Thanks & Regards* *Kannan Prasad* On Wed, May 18, 2016 at 4:31 PM, KANNAN PRASAD <kannanprasad87@gmail.com> wrote: > Hi all, > > > I am using PJSIP library in my iOS application, and I could see that > whenever the messages and send to the application its getting delivered if > the application in in foreground.

Is your app able to receive calls while in the background? It definitely should if configured correctly, and it works for my app. The Getting-Started/iPhone wiki page has a section on what is required for the app to receive calls (and therefore other sip messages) while in the background. http://trac.pjsip.org/repos/wiki/Getting-Started/iPhone#UnabletoacceptincomingcallinbackgroundmodeiOS4 <http://trac.pjsip.org/repos/wiki/Getting-Started/iPhone#UnabletoacceptincomingcallinbackgroundmodeiOS4> In short, your app must connect over TCP (or TLS) instead of UDP, and your app’s UIBackgroundModes Info.plist key must contain the “voip” value.

@Nick, Thanks for your reply, In my case I am getting messages in devices which are below iOS9. Other devices have issue. And regarding the points mentioned by you, I am not doing anything like mentioned in Point 3. And also I am not seeing that error. So assuming it is working in my case. It will be great help if you can share some code which works in iOS9 devices.
