Android :: Droid Convert Phone Number In International Format?

I'd like to know whether it's possible to have phone numbers converted
into international format when a call is outgoing.

For instance, if a french user (sorry it's the only format i know i
won't make a mistake :-) try to call with the national format :
01.47.12.34.56 then a method will convert it into international format
like this : +33.1.47.12.34.56

I've looked into the doc of the PhoneNumberUtils but i don't know if
there is a method doing what i want.
