Getting calls from this number every day, 2x in a row, and the caller hangs up each time as soon as answering machine picks up. Caller ID display doesn't show a name or city. My phone company blocked the number, but they still call back with a variation on the last 7 digits.
I Googled the number and found some more info about it: http://www.ruscammer.com/4242268952/index.html It's supposedly a landline and the carrier is Pacific Bell.
Thanks for the detailed info on how they're getting through the call blocking. Hawaiian Telcom needs to do something about these calls. It seems a lot of Hawaii residents are getting them.
