What I have works, but I would like to get rid
of the POTS phone-line.
When we switched to VoIP with FreeSWITCH here, we made a decision to keep one POTS line as a backup. We got the cheapest service we could find (from AT&T). We get value for our money because we use it as:
Our incoming FAX line (using HylaFAX with a Best Data Smart One 56SK modem from the late 1990's that has worked perfectly for years);
A backup DSL line, plugged into a dual-WAN router. (Our primary Internet is Comcast.)
A POTS line for our alarm system, as highly recommended by our security company; and
A backup phone line, in case a power failure is longer than the UPS run time. (This happened during the California electricity crisis of 2000 and 2001.)
We can keep the cost low because other than the alarm system calling a toll-free number, no outgoing calls are made from this line.
