Hi.
Actually no, maybe I discovered it`s too late. Yes, we had Hylafax with Avantfax and bunch of t38modems and have tonns of problems in interoperability. So what we choose after looking https://freeswitch.org/confluence/display/FREESWITCH/mod_spandsp especially email2fax chapter: I wrote small pipe transport script for EXIM which converts PDF,TIFF,DOCX,DOC to tiff suitable for TxFax.

Hi Volodymyr,

The gofaxip stuff does look interesting - did you try it out?

We use Hylafax because a) it's about the best open-source fax server with a long history and b) It has Windows clients that provide a virtual printer, which is essential for our business (faxes sent via Excel macros)

I've not found any solution that works with FS native spandsp based faxing that can also provide a Windows virtual printer for outbound faxing from the desktop. Faxing via email is not an option, I'm afraid.

Hello, actually in my case we switched from hylafax and emulation of modems (t38modem or built in Freeswitch spandsp modem) to RxFax/TxFax apps combination. Because you need less of layers of software and solution becomes more simpler and stable. 
Did you look on: https://github.com/gonicus/gofaxip project they try to remove layer of modem protocol for Hylafax.

Hi,

I asked this question a *long* time ago as I was having major problems
receiving faxes using HylaFAX and the builtin FS Modems, in that the FS
Modems did not have any kind of flow control, which resulted in a
repeated backing off of baud rate until the incoming faxes failed with a
rate of over 50%.

Has there been any change in the softmodem code to add flow control so
that this does not happen any more?

Best regards

Alex
