I got no reply when I answered just dead air

who is this number belong to

Sounds like a fax machine calling. But no clue who it is.

I have multiple 'faxes' to my business number.  I've called rogers about it and they told me they can't block these callers, even when I tell them the exact number and the caller ID.  This is just awful phone service...

this number (416) 360-1550 claims to be from Bell Canada. I asked them if he was working for bell, but he said he is calling on behalf of bell. Behalf is not the same as directly working for bell. but anyways, I told him i got rogers for hi speed and cell phone but they guy was trying to sell me bell. bell customer service is not good.
