Fax not Working

Hello all

I know fax is unreliable but it does do the trick 75% and I don’t use it as a work horse, but I would like to send and receive thru my email vm.

I have noticed that NVfax detect is not installed is this a new way or do I need to install? After trying to receive a fax I get disconnected from fax server. does anyone have this working. I would really appreciated it and point me in the right direction.

Thank you
my install is the latest
FreePBX 12, Centos 6.5
Asterisk 11
