If you are having trouble with the reliability of your fax machine, or have problems faxing to\from a certain phone number, you may want to try a lower speed setting on your fax machine.  Higher speeds were developed for fax machines to help drop per minute cost of faxing, but it can reduce the overall reliability of the faxing process.  With FluentStream, you don't have to worry about per minute cost, so running at a lower speed is the preferred method to ensure the best fax performance.


  • The best setting for fax machines running over an analog adapter is 9600.
  • This speed is sometimes referred to as "Basic" mode, or "Compatibility" mode.
  • The 9600 speed was first introduced in 1991, and will be supported by almost every fax machine still in use today.
