Free Fax setup

Asterisk, Freepbx 2.9 Beta, Fax Config

If I call the configured feature code for fax which default is 666, should the fax not answer?

I also had the system set for fax detect, I could hear it answer and play ring back, but it would never respond with the fax tone.

I’m not sure if that is what should happen - trying to take it a step at a time.

Have searched for docs on setting the fax up, but most of it appears to be for earlier versions of Asterisk and Freepbx so I dont know if the apply to this version.
