I have received 3 more of these calls since I posted the original warning. I have been trying to figure out a way to make sure that I when I refuse the IP call that I am not depriving a truly hearing-impaired person of this valuable service.

Now the first thing I do is ask the operator to ask the caller where this call is originating from. If it's a local person I plan on asking them to come to the store. Not one of these calls is from a local person so once they tell me where they are calling from - the last one was from Detroit and I'm in California - I ask the operator to hang up.
