asterisk users - Dec 2018 - Asterisk / FreePBX Anlaog Fax behind audiocodes MP112

Hello,

At the moment we have a Swyx phone server.
We would like to switch to a free asterisk PBX.

All phone extensions work as expected except the fax.
This is a analog Fax behind a Audiocode MP-112 FXS.

I have create a extension for the MP112.
The MP112 can register to asterisk.
When I send a Fax to this number I hear a "Modem sound" but no fax is
printing.
