This means that we negotiated ECM with the receiver but then encountered a fatal error. Basically this means that our fax system isn't compatible with theirs. One option for us is to disable ECM and try again when we encounter an ECM issue like this. I'll consider adding this next time I'm working on the outbound faxing system. In the meantime, the only practical solution will be to send a fax by some other means. Do you know what kind of fax machine is on the receiving end?
