SOLVED No Carrier detected

[M4rv1n]

Hi!
I'm a newbie and I'm trying the pbx on a raspberri pi 3. I followed the tutorial and setup a very simple pbx with also fax.
I can receive a fax and route to email correctly, but when i try to send a fax i have the no carrier detected error.
Where's the mistake?

I have a pstn line connected to pbx with a patton smartnode 4112.
Every help is welcome

I found the error. I missed fax configuration on patton. From patton website:
