Making a word look-up list isn't very hard. As bplus said, just take any of the basic SCRABBLE word maker programs and alter them slightly for matches for the various numbers.
The thing I foresee being an issue is getting those "almost word" matches. For example:
1-900-SXY-TIME
1-800-LUV-QB64
1-800-IBSteve
Most phone numbers aren't 100% word matches. They're often missing letters, or "close enough" to the actual word, that most folks can still instantly recognize them. THOSE would the fun ones to try to find and match!
If only someone had a "close enough" Spell Checker of some sort, that they might could check a word list against, to try and get those type matches....
