I did a quick google and someone mentioned that input and output
functions need to be written in C.  Is that still the case?

Anyway, there could be multiple number types to choose from such as:

telephone-us-basic  : (555) 555-5555
telephone-us-extention : (555) 555-5555 ext 1234

Other locals (EU, etc) could create their own to their local
specifications. This would seem like a nice contrib package.
