[Freeswitch-users] FreeSwitch modems flow control?

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.

Alex
