fax won't receive a fax Hp Officejet pro 8710 series.

good morning, I have checked the cord cable and its fine. I did a fax test, but the only thing fail was the Dial Tone detection.  If the fax line condition test passes the using correct type of phone cord with fax pass the phone cord connected to correct port on fax pass the fax connected to active telephone wall jack pass and the fax hardware test pass, why is not detecting.
