I got 6-8 calls from this number this morning between the hours of 4:30 and 5:15 am! I am very mad!

Looking for a device that blocks Fax signals.  I spoke to the spy store here, and they said there are several fax signals now.  Not one device will kill faxes, but there is a device that will block all calls unless you put in a pass number.  I figure this would only serve a person who only has friends/relatives calling that line.  No outside calls without pass number will get thru.Also, had one spam fax call ring thru my phone at 3am on a Sunday.  My phone has a 'Night Mode' where it won't ring, but I know that police and emergency can turn it on with their 'special ringer'.  Well, that's exactly what this spam fax did.  it made my phone ring - Even though I have a night mode.  So I turned the ringer completely off upstairs.  That's the only thing that works.NIce huh?  They get the technology before we can.

I receive calls from this fax nmber at my office at montréal

Fax line Calling our business phone line several times. Tried to fax message back to caller, but it would not go through. We have reported it to the DoNotCall.gov. Our real comfort is that God knows who it is.

Day in and Day out! this is only one of the many. I tried the instructions above, so we shall see how long it takes to work. This is My sole business line so it is important that it is not hogged by these stupid fax services. Not to mention it has never in the 5-6 years I have had it been a fax line.

I tried entering 00000 when prompted then by 604 cell phone number after the first call but I got 3 more calls after that.  How long should it take to remove someone's number?
