Received two calls from this number this afternoon. I have two phone lines and the calls came back-to-back separated by less than a second, which means that they are just doing a phone book attack through an autodialer. Neither call left a message. Just dead air on the machine.
According to complaints left on other phone-spam reporting sites, the callers claim to be from either Bell Canada or Sunlife Financial. They ask for private details, then offer false names and fake return phone numbers when asked to identify themselves.
