Experts - I'm looking for a piece of hardware that will allow me to place calls from a normal consumer analog phone over both the regular old copper phone network as well as a VOIP network. Yes, I'd like to use my existing home telephone on both services. For example: In my home, I have a POTS line and a private VOIP Asterisk server that all my friends are using - I want to:
1. Plug in the POTS line from my local telco (Verizon)
2. Then snap in the Ethernet cable from my home LAN
3. Do some web-based configuration on the device so it knows what the network address, username/password is of the VOIP server.
4. Then plug in our existing normal home telephone.
When placing calls, there should be a little switch on the top of the device that says something like, "PSTN or VOIP." When we call our "geek friends" we flip it over to "VOIP" and dial "*45689." When we call our "non-geek friends", we flip the switch over to "PSTN" and dial "(818) 555-1212." The switch is optional but the functionality should be there. Not required but a bonus would be that if the power went off, the PSTN side of the device would still be able to place normal PSTN 911 calls. Once setup, the soulution should be simple enough to use that a non-geek (like my wife) should be able to use it. The person that will be awarded the points will post a link to the lowest-cost piece(s) of hardware that performs these services in the steps shown above. Does such a piece of hardware exist?
