I've been getting lots of calls from numbers with the same area code & first three numbers as my mobile number. Same with this number. They never leave a message or only a 1 or 2 second blank message in my voicemail. No history here on 800notes. Reckon it's another type of robo call. Possibly masking their number to appear local.
I block them all.    About a dozen  so far.
I don't know you + No Message =
BLOCKED
