Re: [hylafax-users] Large number of failures receiving faxes ~38% failure rate

[Lee Howard <faxguy@xxxxxxxxxxxxxxxx>]

We'd need to see a session log to be able to help.  The final error 
message is sometimes not definitive.

However, given the number of problems you're having it is likely either 
a line problem or a serial communication problem or something else 
seriously wrong with your system.

Thanks,

Lee.
