I missed a call from this number. When dialed it back it said the number has been disconnected.

I too get a call from this number on a daily basis and have just stopped answering, but nonetheless I did an internet search and found a link on the internet which i've attached for your reference.  This link is a fax # for a telemarketing company, not a toronto payphone as some people believe it to be. Hope this info helps. http://www.toronto.net/Directory/R32S.html

A FAX machine calls our Support desk.  If answered a series of beeps comes through if not answered then our answering machine captures the series of beeps.  I have requested the company, fxstrategy.ca to stop dialing our number but to no avail.

I called the actual Fax # at the 1-905-248-3652 on Caller: fxstrategy.ca and requested that they remove my number.
I duly noted that they were noted as a Mass Fax/Spam type company caller to many persons online, and that they are noted on many web blogs as such.  I would encourage everyone to leave them a message or even fax them back.  Discouraging to even own a phone number at this point!

I get calls from this number and it is someone trying to send me a fax.
I went to the website that you posted (http://www.toronto.net/Directory/R32S.html) and see that they say on their webpage that their fax number is 416-361-1979 and they have an email address on the webpage also.  I emailed them and asked them to stop calling my home phone number and this is the reply that I got ...

Sorry. We do not send any promo material via fax.
