I can confirm this as well.

I got one call today too. 8h27 ...  M02280827140047  ...  (519) 804-2222  IDnobody spoke but  this person breathe

Received a few calls from this number, with no message left. The calls seem to come in shortly after 6am PST. Calling it back connects to freephoneline.ca's IVR. Following this through to a person ended up on a line with so much distortion I was barely able to pick out every third word the operator was saying.The bits I was able to salvage from the call suggest it was a sales call, aiming to sell me their ATA.

i think i know what it is. When you register with freephoneline, they call the number you provided while signing up to confirm the number. its would just be a validation call.

Got a call from them today. Lots of noise on the line. Person mumbled something totally incoherent, sounded like a different language, maybe an Indian dialect. Caller ID showed m11161541150038.

I signed up for freephoneline.ca last week. Since they I have received a couple calls from US numbers that have been reported as fraud lines. I wonder if there is a connection.
