JD, thanks for the detail. So, I would need a spare PC and a Sipura 3000
($90-$100).
What would the physical layer look like? Something like this?
[Sipura]
[ FXO ]<---POTS Line
[ FXS ]-->Cat3Block-->3 analog phones
[ 10bT ]-->Asterisk PC
Also, what is the failover plan if the Sipura loses power? Any chance it
fails "open" and just passively passes dialtone from FXO to FXS? (stop
laughing)
For that matter, what if the Asterisk server loses power or network
connectivity?
