Extension routing module pins and follow me problem

We are using the extension routing module to manage mexico based cellular calls. It ends up being quite complex however the fundamental problem is follow me does not carry over the rules. SO, a call comes in to an extension that has permission to dial a route, however follow me asks for a pin. certain cell phone numbers as an example are listed in the dial pattern. dialing from an approved extension = call goes right through as expected. incoming to that extension, follow me trys to go to that cell phone and a pin is requested.
