I had a very good success rate with multitech modems connected to fxs card
and calling out with T0 (bri) I had 3 modems in total, - 1 receiveing 2
sending, they were heavily loaded and i had very low failure rate 20 000
faxes and only 3 failed (!) from 3 only one due to incompatibility (brother
model know issue) and 2 bad line. I dont inclide here wrong numbers.
