Background mode working only when i launch my app from xCode.

Hello all,

I am using PJSIP 1.12.. I did not run any special config when I compiled the libraries.. just compile for ARM6 and ARM7 then merge.. I am trying to get background working so:

-  I used TCP instead of UDP as my protocol.

-  I checked PJ_ACTIVESOCK_TCP_IPHONE_OS_BG and PJ_IPHONE_OS_HAS_MULTITASKING_SUPPORT in OS_autu.h and I see both of the defined as 1. I see both of them defined in a ?#if defined(PJ_DARWINOS) && PJ_DARWINOS!=0? so I did not change anything...

-  I added Required Background mode flag into my test App plist file

When I launch my app from xcode by hitting the play button, then  I press home on the device to put the app in background mode I see the my registration function gets called every 60 seconds as expected. and when I call the device I  hit the on_incomming_call event as expected.... 


But when I launch the app from the device itself just click on its icon the background does not work.. if I tried to call the device after 60 seconds, Astersik will say the device is not registered which mean the background socket did not respond to the Keep alive thing between the server and the device..


if I removed the plist entry about background mode It does not work in both cases (launch from xcode and launch from device), so I think I am on the right path...


Am I missing something else?? I have been researching this issue an I am not sure what is missing?

Thanks,,,
