Hi Filiberto,

From your attached configuration file, I found out you didn't configure voice port in your dial-peer

dial-peer voice 112 pots

description FAX 1190

destination-pattern 1190  --------------->faX NUMBER

If follow your description in your configuration you should configure a voice port in this dial-peer as below:

dial-peer voice 112 pots

description FAX 1190

destination-pattern 1190

port 0/2/1

Regards
