Googling on 1-888-902-9998 finds an interesting discussion thread:

http://www.tek-tips.com/viewthread.cfm?qid=583069
which includes these useful notes:

"Also check out 888-294-9681 - it gives you the voice circuit type and
the number... will even do callback at the end of the call to confirm
that it is working fine."

and

"Here is a nation wide ANI # from MCI 1-800-444-4444"
