flexfax: reliable faxmodem?

[Ralf Graefe <ralf.graefe@ecrc.de>]

Hi there,

who can recomment me a really reliable faxmodem for Hylafax? Till now I
used an U.S. Robotics and a Zyxel Elite 2864D. The first one most of the
time claimed that there is no answer on the other side and the Zyxel
always has problems if talking to an ISDN Fax.

Thanks, Ralf!
