One of the returns for our phonathon is a listing of bad and wrong numbers which would range over different phone types. i.e. home. business, cell, etc. Has anyone figured out to import across these phone types to label the phone numbers as bad numbers?

You would probably have to do this with a custom function. You would need to look through all of their phone numbers for a match and then set that as invalid. See this thread for a good start on looking through the numbers on a record.
