Hi there, I have google'ed and wiki'ed for days now and get nowhere. I tried all the spandsp versions with all the recommended libtiff versions and the best I can get is: Rxfax works with spandsp-0.0.2pre21 and tiff-3.7.1 from source TxFax gives me some of the fax but it is messed up. I have done all the gain adjustments What I would like is for someone to answer me with what works for them, and I mean sending faxes not just receiving faxes. I forgot to mention that I am trying to send a fax via a TDM card and not over IP. It's like this: Asterisk--->TDM Card--->PSTN---->fax machine The method of sending a fax file is via a call file.
