You might also wish to look at the Asterisk

OpenSource PBX software for Linux systems.
Asterisk would be a great solution as well but the boards required to make
it work might be more expensive than a cheap PBX. You'd need to use telco
boards that could implement modem tones on their ports, which are
available but pricey.
If you google around, or just check out their mailing lists, there
are some pretty cheap options.
I still think you're right - a small used PBX system is probably the
cheapest solution.
