[hylafax-users] Problem Receiving Faxes

[Steven Jardine <steve@xxxxxxxxxxxxxxx>]

I am have been running hylafax for years now on my Mandrake Linux 10.1
system.  It has 3 - MultiTech (LT V.92 1.0 MT5634ZPX-PCI-U Internal
Data/Fax/Voice Modem Version 1.32i) modems.  We use them for receiving
only and they are configured for class 1.0.

The problem it that occasionally we recieve faxes that give "MODEM No
carrier" messages.  The messages seem to originate from the same fax
machines and those fax machines return "Poor Line Quality" messages.  I
have tried to fix this by adding "Class1ECMFrameSize:     64" to the
config file but it doesn't help.

Any idea's?  I have attached the config file and log file.  Thanks.

Steve
