Yes, Softlinx can block faxes (outbound and inbound).


  • On the spam filtering front, we do not currently have a means of filtering out spam, as it would require a major rework of our system.
  • We only block spam faxes, not just any number.
  • Determined spammers can get around filters and blocks by using alternative numbers. If possible, it is always best to work with the sender to see if an inbound number can be blacklisted on their end.


  • In the event that a recipient requests that we do not send any faxes to their number, we have a means of blacklisting that number in our database. Once blacklisted, all faxes to that number will end up in automatic failure.
