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.
