MMR was used.

Don't know, users say "some receivers sometime/rarely, other receivers
often".

Users say today it happened for 3 jobs in a row to the same number, so it
happened even without RTFCC being performed (at least twice)

Modem was being used in class2.1. Is EOR visible in log if ECM is performed
by modem? Today I quickly looked at the logs and they were perfectly clean.
I'll see if tomorrow I can check again.

Yes, this is what I meant; I expected the modem would pass some kind of
error about persistent ecm crc failures to HylaFAX.

Tomorrow I'll see if I can get a log, but as I said they were class21 and
clean.

Thanks.
