Re: [hylafax-users] T.30 T2 Timeout, Digital Phone Lines and Modem Speed

["Brad Stevens" <bstevens@xxxxxxxxx>]

I'll have to differ to all the others who answered this problem in the
past, as they found the problem I just passed it along.  The good part
is Hylafax works great with the Multitech. The bad part is that older
versions of Hylafax used to work great with the old USR modems.
Something changed that made the USR compatibility go downhill fast.  I
started using Hylafax because I had an old PC and old USR modems laying
around.  Worked great. I decided to upgrade to a PC that had more PCI
slots so I could add more USR modems that I had laying around, and so I
upgraded Hylafax to a newer version as well. Well, long story short, I
ended up spending a couple hundred bucks on new modems to get rid of the
issues with Hyla and the USR modems.....go figure.

Just to close this issue out, I replaced the USR modem with a  
Multitech MT5634ZPX and I haven't had a problem since!
Thanks Brad!
