Nope, the error is from getty, which is run to initiate the fax connection
(i think)... i've been looking all over for getty errors, but i just can't
seem to find any docs on them.
My only guess is that, since this was an international call, the
machines didn't have enough time to negotiate a connection... So I've
added a line to my config.cua1 file that reads something along the lines
of: ATS7=90, which sets time to wait for a connection to be negotiated to
90 seconds.

Fax class is 2.0. here's one log:
Jan 10 21:15:23.88: [   91]: SESSION BEGIN 00000005 ********* (fax number
edited out)
Jan 10 21:15:23.89: [   91]: <-- [4:ATA\r]
Jan 10 21:16:17.30: [   91]: --> [10:NO CARRIER]
Jan 10 21:16:17.31: [   91]: ANSWER: Ring detected without successful
handshake
Jan 10 21:16:17.31: [   91]: SESSION END

Then, on a second call from the very same fax machine, HylaFAX generates a
different log:
Jan 10 21:17:02.80: [   91]: SESSION BEGIN 00000006 18476570217
Jan 10 21:17:02.80: [   91]: <-- [4:ATA\r]
Jan 10 21:17:22.15: [   91]: --> [4:+FDM]
Jan 10 21:17:22.15: [   91]: ANSWER: DATA CONNECTION
Jan 10 21:17:22.15: [   91]: GETTY: START "/sbin/getty -h cua1 dx_38400",
pid 4$
Jan 10 21:17:22.28: [   91]: GETTY: exit status 0400
Jan 10 21:17:22.28: [   91]: SESSION END

Another call from the fax machine (which is located in Korea, I'm in USA)
generated exactly the same log, only with different time stamps.
