A SPA122 ATA from Cisco might be useful as a gateway, they are cheap.
You´d be using it kinda in reverse, but I don´t see why that shouldn´t
be possible.

Other than that, specialized cards have come down in prices, probably
because ppl aren´t using them anymore.  You might also want to look
into Patton gateways, but they tend to be rather pricy and are a hell
to set up unless you´re familiar with all the phone-related stuff.

If your internet connection is decent, it might be a good idea to give
up the POTS line and use a VOIP provider instead, with a asterisk
connected to it.  It would be the easiest way by far.

Asterisk isn´t too complicated for getting basic phone services to work
on which you can expand over time; you only need to overcome the few
first steps.  Since a Centos package for asterisk is missing, you may
want to compile it yourself, which is easy.  However, I had to disable
one of the drivers/features of asterisk in the build config because
there´s a bug that makes asterisk fail when that feature/driver is
enabled --- I left everything else enabled and don´t know what most of
the stuff is ...

There´s probably no way around asterisk anyway.  For fax, if you really
need that, there is, since ages, hylafax, which apparently can be
somehow made to work with asterisk.  Fax has always been, and still is,
a PITA.  Fax doesn´t make any sense since decades; it´s way easier and
far more reliable to send emails instead.

If you pick a VOIP provider, they might have a fax service which you could
use instead of trying to figure it out.
