Initiate a call programmatically from an IPhone program

Does anyone know the class or code to start a phone call from within an IPhone program?

all I can seem to find is code to do this within safari <a herf="tel:1-555-555-5555">1-555-555-5555</a>

I want the same effect as the code above but from within an iphone program.
