<p class="MsoNormal">I recently just completed installing several Cisco VG204
& VG202 gateways at my office. We use a mix of real fax machines and
a Linux server running Hylafax. The Hylafax server is used only for
receiving faxes. No users use the Hylafax server to send faxes because we
have real physical fax machines located strategically throughout the office.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">When receiving faxes to the physical fax machines, the faxes
are received just fine. However, when faxes are received to numbers
associated with the Hylafax server, we run into an issue. Some, if not
all received fax pages end up being “cut off”. That is, there
is random garbage near the end of a fax page which is unreadable.
However, everything above that garbage is readable & faxed fine.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Prior to migrating to the VG gateways, all received Hylafax
faxes were normal. I’m thinking it has to do with the way my faxes
are set up on the Voice Gateway. Below is my relevant config on the VG202
(the config is identical across all the VGs). Any ideas? I’m
using SCCP for all my phones because I was told it was the easiest &
recommended way to set up the VoIP network.</p>
