Answer 1

Try using the tel protocol.

if ([[[UIDevice currentDevice] model] isEqualToString:@"iPhone"])
{
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel://%d", number]]];
}

You cannot block any incoming calls.

You can't block any incoming calls in your app.
