Fax has worked great for quite some time.  We can still receive faxes, but all of a sudden we cannot send them. We get error message 388.  After running a fax test, the results showed Fax Line Noise Test--FAIL.  High frequency noise detected.  The solutions talk about DSL/ADSL service but we don't have that.  I hooked my phone up to the phone jack and could not even get a dial tone.  When we try to fax, we can hear the tones of the number but there is no ringing at the other end--just a too soon sound of the fax receiving whistle.

If you get no dial tone when using a phone then you likely have a line issue or another device that is interfering. Have you phone provider confirm the line.
