Cut and paste what you want, then add a "&start=32" to the end of that URL to get the second set of 32. Keep incrementing that start number until you have all the names.
Of course, if this is something you'll want to do often, you could make a copy of the xmldirectorylist.asp file, go in and edit the maxListSize variable to be some number larger than the number of entries in the directory. Then you will get just one list. Just make sure that the phones still refer to the original, because the phones will not act as expected if the try to display more entries per page.
