No message left even though call went to voicemail (suggesting a robocall system). Caller ID said "BROWNSVILLE PA" (with space in the middle like that). Another report site had it flagged as a car warranty spam call.

Didn't recognize #; caller ID just said "HONESDALE PA" (yes, with the gap in the center). Googled the # and another report site had ALREADY flagged it as some sort of health insurance spam call....

6th call from "SAYRE PA" since early March. Only difference is the last 4 digits each time. This time? Picked up & immediately hung up when I saw the caller ID....

HAS to be some sort of fraud: the caller ID came up as "NOT IN SERVICE"! Did not recognize # and for the most part neither did Google (I'm fixing that -- you're welcome...).

No message left by "Name Unavailable" even though call went to voicemail. Another site ALREADY had # flagged as "invalid or not belonging to the US" when I looked it up! Clearly some flavor of scam....

6th call from this area code/exhange in a month. 27th since Jan. which came up as "Name Unavailable" on the caller ID. NO hits on Google. And another report site said # was either "Invalid" or "NOT a US #". I'd call that a Fraud Call, too....
