If you're looking for completely accurate time accounting for call 
connect time you cannot trust the "time" given in HylaFAX xferfaxlogging 
because the modem (and thus HylaFAX) is usually unaware of the exact 
time when a call is answered or disconnected.  HylaFAX gives "modem time 
off hook" as the stated job time.  So, it's not surprising that you'll 
see discrepancies between HylaFAX and your phone system with regards to 
on-line time.

HylaFAX intentionally is liberal about the amount of time it calculates 
for job time.  So the actual time used between call answer and call 
hangup is always going to be less than or equal to the time reported by 
HylaFAX as "job time".

If you have to bill based on xferfaxlog time information then you can 
either subtract the average time overage from the given time amount, or 
you can merely obligate your customers to pay for the time overage and 
make it clear that the time is calculated as "modem time off hook" and 
is not "actual call connect time".

Thanks,

Lee.
