It would actually be a neat UI to show the person's contacts letting the person pick which one to try with a "match the hash" function that shows the one way hash generated and does a "ping" on the service to see if someone matches.
Won't happen, but would be a fun UI to do.

North America only has 10M possible phone numbers so brute forcing or building a rainbow table is trivial. I don't know about other country codes but I presume the situation is pretty similar.
