A Sipura SPA-2000 provides two FXS ports for two analogue phones.
You can use a bunch of these devices if you need more ports.  Of
course, once you get to a certain number, a channel bank will be
cheaper.

A Sipura SPA-3000 provides one FXS port, as above, and one FXO
port for your phone line.

The configuration quoted above (2 x SPA-2000 and 1 x SPA-3000) will
provide 5 x FXS ports and 1 x FXO port, and should cost less than
$350 USD.

If you need a hardware timing device for some reason then a cheap
X100P will do the trick.  The software timer modules should be ok,
on a Linux 2.6 kernel, for most uses.
