[asterisk-users] Problems with Fax over TDM410P

[Danny Dias]

Hi asterisk-users

I'm really having big problems with this configuration, has anyone attached
a fax machine to a FXS port of a digium tdm410P card succesfully?

What changes should i do on asterisk to make this work ok?

I just want to use this fax machine as a fax and not to voice!

Thanks!
