When running elastix 1.3 with a sangoma a200 with hardware echo, I have no problems receiving faxes. If I upgrade 1.3 to 1.5.2 I don't seem to have any problems either. However if I stall right from 1.5.2 I have major problems with incoming faxes to hylafax. I've back revved my customers to 1.3 due to this fact, I'm not 100% sure whats causing this but faxing is really broken. in 1.5.2 Is anyone else having this problem?
