I would use the free analog line for a PSTN failover, e911, and FAX
line and then get SIP trunks for the main business lines. Fax doesn't
work well over VOIP. Does the TWBC phone line work even if the power
goes out? This also seems like a good solution for Freeswitch via the Bluebox distro. See http://www.2600hz.org/downloads/. You would buy a 2FXO/2FXS PCI card from Sangoma and put it into the server. Then connect analog phones to the 2 FXS ports and set up a ring group to ring both phones when either of the FXO trunks ring. I've never used Bluebox, but I've used Trixbox which uses the FreePBX GUI, and the GUI is excellent. Bluebox would be an improvement over Trixbox since its not using Asterisk as the back-end. If they want to save even more money, they could still switch to SIP trunking and use either the Bluebox or sipXecs. For only 2 phone lines and 2 internal extensions, it's a toss-up. I've got a Trixbox server at my home running on a Pentium4 2.66GHz w/ 512MB RAM, and it's run just fine for 3 years (after the initial bug workarounds), so the server doesn't have to be as powerful as you'd need for sipXecs.
