yes, anonymous monk, to clarify LAI's point, I need to be able to do this because I'm helping to make a voice synthesizer and in human speech telephone numbers are usually realized differently from e.g. an integer, especially in many romance languages like italian, which is what I'm working on. I don't have any intention of calling anyone with this information, nor am I trying to extract phone numbers with the aim of calling these people up.
