You can use this code to enable call from your application.

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://0123456789"]];

make a UIButton of custom type and as Caption set a number to display... so it will display only one number (button won't be visible...) and on button's click event Call that particular number by

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://1456987452"]];
