I have not had much luck with tx_fax and spandsp. I am using centos 4.4 and spandsp spanshot from Dec 9. I have tried both a TDM2402E card and a T1 card with no hardware echo cancellation. I am getting the same results with both cards. I am using asterisk 1.2.13. I might receive 1 page or 3 or 2 pages of 3 but never 3 full pages. Also having received the fax (fax machine has hung up) the fx_fax continues to run for some time. I have tried two diffenent fax machines also - with the same behavior. 1 is an actual fax machine the other is a fax service. Seemed pretty straight forward to install spandsp and the two files for asterisk and apply the patch. Any ideas why I might not be getting successful faxes? Do others experience this also? I am not using VOIP in this mix. The server makes calls directly on the same box out the analog or T1 lines. THanks, Jerry
