Re: [hylafax-users] MultiTech ISI5634UPCI/8

Hi All,

Just as a general question.  I have 2 of the ports dedicated to receiving
faxes from only a couple customers.  These are larger businesses and I
receive 100% of their faxes correctly.  Then 3 of the other ports are in a
hunt group, and we receive faxes from small businesses (audit records)  I'm
guessing that the faxes we receive from the 2nd group are coming from a lot
of cheap fax machines and or fax/modems.  Is it realistic to think that I'll
ever receive more than 90-95% successful from that 2nd group given the vast
number of different fax machines??

Thanks
Chris

I don't know if this is related. However I recently pretty much eliminated
the above error by downgrading the firmware on another brand of
multitech modem (MT5634ZPX-PCI-V92) from 1.32i to 1.25p.

I would assume there is some common code between the different firmware
and it might be the cause of your problem.

Steve Tuckner at Multitech provided me with 1.25p firmware awhile back.
He might be able to shed some light on the potential problem you have and
the one I had.
