[hylafax-users] Problem Ring detected without successful handshake

["Scott Rasco" <scottr@pbminc.com>]

Running Hylafax 4.1 Beta 3-1 / Libtiff 3.5.5-2 on RedHat 6.2

Problem with “Ring detected without successful handshake” for some incoming
faxes.  I am using an Intel 144/144i internal faxmodem set for class 1. As
you can see, the faxaddmodem script recognizes my modem as a 400e, and seems
to work with most faxes.  I did have a problem with some incoming faxes
where I would get a MaxConsecutiveBadLines errors, but by setting it to ‘0’
seems to have covered that problem.  Can you provide any suggestions or
comments?

Config File as follows:
