telprint is a package for formatting German phone numbers. Current version is 1.6 and is the first version that goes to CTAN. Some previous versions were published in de.comp.text.tex or TEX-D-L. Unhappily most documentation is in German and remember that this was written in my early TeX days.
Thanks for the upload.
