[Asterisk-Users] Small office setup/using analog lines w/ Asterisk

[Michael Graves]

I too have had trouble with FXO interfaces. I tried the Sipura SPA-3000
FXS/FXO device , X101p cards and a TDM11B card. None were satisfactory
for my small office with 6 extensions and 3 lines.

My longer term workaround was something that I setup just to bridge a
perioud when I was taking down a test server and putting a poduction
server online. I put provider based call forwarding on my POTS lines
(only 2) and forwarded them to my IP based 800 number. This turned out
so reliable that I have remained operating this way ever since, about 4
months now. People have remarked that the call quality is superb.

I ever there is a problem with my DSL line or * server I simply turn
off the call forwarding using a pair of analogue phones that I leave on
the POTS lines for just such emergencies.

This only addreses incomming calls. All outgoing calls are handled via
IP through another termination provider.
