Here's the relevant portion of the log...

The translation here is ... this was a batch of jobs.  We send the first 
job/document and terminate it with an EOM signal... which means end of 
document, but more documents are coming.

After hearing MCF to EOM the sender is supposed to just sit and wait, 
listening for the receiver's Phase B signalling (NSF, CSI, DIS) - yes, 
after EOM the fax procedures go back to step 1... EOM is merely to save 
ourselves from placing another call or to allow document formatting to 
change.

The sender is supposed to expect to wait for maybe up to 7 or more 
seconds of silence before hearing the receiver's Phase B... because the 
receiver is, per spec, instructed to just wait that long before 
proceeding.  However, 2.14 seconds after hearing MCF the modem reports 
that it hears V.21 HDLC signalling (which would be okay, HylaFAX is okay 
with receivers who don't wait a full 7 seconds there)... but then that 
signalling stops... and then HylaFAX enters recovery procedures with CRP 
and the receiver disconnects (with DCN).

So... either the receiver does not support batching (normally HylaFAX 
can detect it, remember it, and will disable batching to that 
destination from then on - which did not happen in this case... thus you 
had 30 phone calls and 29 errors), or your modem is incorrectly 
reporting V.21 HDLC detection.

If this is a Lucent/Agere/LSI-based-chipsetted modem (Multitech 5634 or 
Mainpine) then you need this in your modem configuration file:

Class1HasRHConnectBug:  yes
