Received a phone call just before 1PM EST Oct.31. 2011. Call display indicated call was from SIPP no one speaks - just dead air. When I phone the number, this number is not in service message? I have noticed other people are receiving similar dead air calls where the call display indicates SIPP, but the number displayed is different: 416-657-4062.

Getting the same call said sipp from 416 481 6266

Same here, i have it showing up on my call display 8 times today alone. SIPP has been calling me for the past 2 weeks at the exact same time(s) everyday +/- 10 minutes. Anyone know what/who this is?
