X100P and incoming fax with recepcionist

Hello.
I have asterisk, freePBX and one X100P card, all configured and running on my SME server.

The problem is: when an incoming call, I can take this with the SIP extension that is configured for it, but when transfer the call to the 666 to receive a fax through the system, the system takes the call but never responds fax tone, then the issuer hang up the call .

With the following commands:

I see certain things I would like to change to see if it resolves the problem and improve the audio quality, but I don´t know how.

Fax Handled: no --> Fax Handled: yes

Nor I know how telling to the FreePBX´s fax system that detection method for faxes is Zaptel (remember I have a X100P card), the option is only for trunks.

Once work well only for fax dedicated trunk, by modifying the settings of the trunks, but this is not the case, I want to transfer the call to fax through the system 666 when necessary.

somebody help me? :smiley:

Thanks
