Dear Cheers, 

Thank you for your reply. What if UDP is a must, is there any solution for this ?  

I found some possible solutions shown as follows.
1. Client periodically registers to SIP Proxy within 3 mins.
2. Play audio streams when an app runs in background mode.

Any comments for this ?

Dear all,

I tested the Linphone with iPhone4 iOS 5.0 and iPad2 iOS5.1.
When LinPhone runs in background mode, it cannot receive any VOIP call.

Has this issue been solved or no solutions ?

Hi, in iOS, as far as I know, UDP sockets are closed when phone goes to background. If you want to receive calls in background you should use SIP over TCP.
