I have used flowroute very successfully for fax sending and receiving. The solution I use includes switching various options on and off for each try to have the most success without a complete failure in years (when sending to a fax machine that is). I have posted some stats that are in the mailing list archives and some details in the wiki. soft faxing seems to work without issue with high reliability. ~Mitch On Fri, Jul 11, 2014 at 9:30 AM, <bruce@sqls.net> wrote:
Thanks for the information. Would you be willing to share more information? Like the SIP providers you're using, type of internet connection, hardware, etc? I would understand if you can't share everything. But seeing that you seem to be having excellent success I would be very interested to know your setup in more detail - might give me some ideas on things to implement or improve.
I do like the combo of FreeSWITCH/SpanDSP + Scripts. I've really liked the lua scripting integration that lets me add console commands and stats info right into the fs_cli tool. So, very encouraging news.

After extensive testing using decent SIP providers (with or without T38), we have much better success with spandsp than hylafax. We even have a better success rate compared to most combinations of ATA + physical fax machine we tested!!
No tweaks needed, and using default values (use-ecm=true, disable-v17=false).
Feature-wise it's not really comparable to a Hylafax solution, but with a few scripts to manage queues and such, you can build a very nice solution able to handle a huge fax volume!

Great, thanks for the idea! I'll definitely give this a try as well.
Also, great looking project :) I'll take a look at it as well. I've been wanting to learn more about golang too. I've used Hylafax in the past but I haven't used it lately - I probably should take another look at that as well.

For received faxes I get a lot more failures then I would like however, close to 15%
I had some success with disabling T.38 for received calls. If i see that negotiation failed multiple times or the fax aborts with errors during page transmission, I save the callerid and disable T.38 when the caller retries. Most cases that were not successful with T.38 worked fine with soft modem. See https://github.com/gonicus/gofaxip#fallback-from-t38-to-spandsp-softmodem for details.
