The id read Connecticut. There was no message. The 555 is never used for numbers. It is for directory assistance. It is used on television and movies as it will never be a real number.
Got this call today. Didn't pick up because the 555 told me it was a bogus number. Area code + 555 + any 4 digits should always get you directory assistance for that area code. That's why every movie and TV show always uses 555 in the phone numbers they show.
