GCDAsyncSocket background VOIP

Question

I\'m trying to implement this(Configuring Sockets for VoIP Usage) using this(CocoaAsyncSocket). To the best of my knowledge step 1 I have done, adding VOIP to background servic

Answer 1

so i believe i have resolved the issue but need further testing to be 100% sure. Currently i ran a test with this code for the length of 21mins of suspended time and it worked

step 2:

 [socket performBlock:^{
                 [socket enableBackgroundingOnSocket];
             }];

step 3:

- (void)applicationDidEnterBackground:(UIApplication *)application {

     inProgram = FALSE;
     showedCall = FALSE;

     BOOL backgroundAccepted = [[UIApplication sharedApplication] setKeepAliveTimeout:600 handler:^{ [self backgroundHandler]; }];
     if (backgroundAccepted)
     {
          NSLog(@"VOIP backgrounding accepted");
     }

}

this seems to keep my client running so from here i add an observer to wait for my incoming call packet and launch a notification when that packet is seen

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{  
     if ([keyPath isEqualToString:@"currentDigitalJoin"]) 
     {
          switch ([[cClient currentDigitalJoin]intValue]) 
          {  
               case 1000: 
               {   
                    if (showedCall != TRUE && inProgram != TRUE) {
                         NSLog(@"incoming audio call");
                         UILocalNotification *localNotif = [[UILocalNotification alloc] init];
                         if (localNotif) {
                              localNotif.alertBody = [NSString stringWithFormat:@"Incoming Call."];
                              localNotif.alertAction = NSLocalizedString(@"Accept Call", nil);
                              localNotif.soundName = @"alarmsound.caf";
                              [app presentLocalNotificationNow:localNotif];
                              [localNotif release];
                              showedCall = TRUE;
                         }
                    }
                    break;
               }
               case 602: 
               {   
                    if (showedCall != TRUE && inProgram != TRUE) {
                         NSLog(@"incoming audio call");
                         UILocalNotification *localNotif = [[UILocalNotification alloc] init];
                         if (localNotif) {
                              localNotif.alertBody = [NSString stringWithFormat:@"Incoming Call."];
                              localNotif.alertAction = NSLocalizedString(@"Accept Call", nil);
                              localNotif.soundName = @"alarmsound.caf";
                              [app presentLocalNotificationNow:localNotif];
                              [localNotif release];
                              showedCall = TRUE;
                         }
                    }
                    break;
               }
               case 513: 
               {   
                    showedCall = FALSE;
                    break;
               }
          }
     }else if([keyPath isEqualToString:@"currentDigitalJoin"])
     {
          switch ([[cClient currentDigitalJoin]intValue]) 
          { 
               case 602: 
               {   
                    showedCall = FALSE;
                    break;

               }               
          }
     }
}
