You can use devices called ATAs (Analogue Telephone Adaptors). They are
much cheaper.

If it's because you have the phone lines already installed and need to
just use them at certain times, I do think there are FXO devices but
I'm not sure they will help. You wouldn't need two asterisk servers at
any rate but only one. The phones connect (through a router if need
be) to the asterisk at the phone lines + FXO end.

Good, higher-end ATAs and IADS will be able to trunk to each other, and
do FXO and FXS signaling on their analog ports.

Two grandsreams, a 4008 and a 4108 would inexpensively do this for you. Instructions are on their site.

Sorry to jump in on this but I am also interested in this topic.
In my scenario I have about 10 POTs lines brought into the front of a
facility and the only infrastructure connecting the back of the facility
is a 3000ft fiber backhaul. I've been asked to bring the POTs lines to
the back of the facility.
Are there any ATAs that trunk multiple POTs Lines? Like a multiplexer
of some sort.
If anyone has any information can you please provide the manufacturer
and model of the device?
Thank You,
Dennis

There are a couple of companies out there that make 24 port fxo and fxs boxes. If you have some unused fibers you cout do this very reliably with two channel banks... One with fxs ports and the other with fxo ports and t1 media converters.
The grand stream solution mentioned in an earlier post does 8 ports, you could get one 4 port model and one 8 port model of fxs and the same of fxo and accomplish your goal rather inexpensively as well.

In generaly this is a bad idea (especially dialup internet). If both the
gateways you use support T.38 origination/termination then faxing will not be
a problem at all.
However, in your case I assume you are only transporting the calls over LAN,
and there is no WAN/Internet involved... which means you will probably achive
a high success rate for both dialup and fax... I wouldn;t be surprised if you
can;t max out the baud on your dialup internet connections though... i'd
expect a slight reduction in speed (and errors, though error correction built
into your modem would hopefully take care of this, at the cost of a a little
speed due to re-transmissions)
