You should check the CTCall's callState property in order to catch it

Use a cellular call’s CTCall object to obtain an identifier for the call and to determine the call’s state.

 extern NSString const *CTCallStateDialing;
 extern NSString const *CTCallStateIncoming;
 extern NSString const *CTCallStateConnected;
 extern NSString const *CTCallStateDisconnected;

are string constants. You for loop doesn't make sense.

NSString *phoneNumber = [@"telprompt://" stringByAppendingString:@"9723539389"];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

self.callCenter = [[CTCallCenter alloc] init];

[callCenter setCallEventHandler:^(CTCall* call)
{
    if ([call.callState isEqualToString: CTCallStateConnected])
    {
        NSLog(@"Connected");
    }
    else if ([call.callState isEqualToString: CTCallStateDialing])
    {
        NSLog(@"Dialing");
    }
    else if ([call.callState isEqualToString: CTCallStateDisconnected])
    {
        NSLog(@"Disconnected");

    } else if ([call.callState isEqualToString: CTCallStateIncoming])
    {
        NSLog(@"Incoming");
    }

}];

NOTE:

  @property(nonatomic, strong) CTCallCenter *callCenter;

should be declared in Appdelegate and retain it. Otherwise it will be considered as local variable & deallocated as soon as come out of loop

UPDATES:

TO ANSWER "callCenter is declared in appdelegate, how can i use it with self? and other thing when [] added to that block then it shows error on equal to "expected ']' ""

replace self.callCenter with these lines

   YourApplicationDelegateClass *appDel =(YourApplicationDelegateClass*)[UIApplication sharedApplication].delegate;

   appDel.callCenter =  [[CTCallCenter alloc] init];
