Hello,

To be honestly we havent tested fax over tooway, but voip works fine. In the old days our customers were using fax over legacy satelitte links without problem. in order to able to use fax over satellite;
- the link should be optimized for low jitter , low latency
- fax machine parameters should be optimized for the satellite link.
- VoIP/FoIP device parameters should be optimized for the satellite link.

If you give more detail on how you set up the fax i can help you.

regards,

I started having severe difficulties with fax as soon as I used IP telephony, even over ADSL, and intitially had to keep the analog line as ADSL support anyway, so I connected my multi-function printer's telephone port to that, for fax only, but when I want to Tooway I had to abandon fax altogether. Not a problem in the north-western world, but I can imagine it is when you trade with Africa and other areas still using fax a lot. I'd try to set the transmission speed to a fixed, rather low speed, using a "good" old fax machine that allows that. It looks like the auto-negotiation sequences (trying highest speeds first) end up making wrong, optimistic assumptions, or just fail, and the fax transmission either never starts or the link breaks up due to the packet-jitter inherent to all VoIP networks. Humans can absorb little flaws in a voice transmission much better than machines can.
