This caller blew up my phone 3 times last night within a 4 minute period, I thought it might have been a friend from Toronto, so I answered. The first 2 times there was silence on the other end, the 3rd time I ignored it. It went to voice mail, they left an silent voice mail. Within minutes, I got 2 more mysterious calls, 1 from 313-918-1326, unlisted, untraceable, unknown to me, and another from 760-705-8888 (a google phone caller). This screams out to me as scammers fishing for victims,  Use caution when answering from either of these numbers.
