I have been using hylafax for over two years. We are running RPM
for hylafax version 4.2.0, which we are running it on RHEL version
4. We have been running two servers one analog with 16 modems and
one using VoIP. We understand that VoIP isn't liked by all on the
list especially. However, our application has compensated for the
failure rate we have seen on VoIP. We went to move all our lines
to VoIP lines because of cost. As soon as we did, our error rate
went through the roof. We made sure we had enough room for the
VoIP bandwidth-wise and that's no longer an issue. I am trying to
see if the free version of hylafax has some limit on the number of
modems that are best to use? Is hylafax threaded? At this
point the only change to the system are the number of modems.
