I've been getting a spam fax on my voice line at all hours of the morning for the past few days, so I started to try and figure out how to contact the company to get off the list.. I went to Shaw's site to see what they could do and found out they have a call rejection service built right in!
Just add the number to a selective call blocking list and bam, no more calls.
Impressive!

Just wanted to share in case you had this problem.
