[asterisk-users] AA50 Failover

[Dave]

 From my research, it seems that for FXOs you can use a siple RJ11  
splitter. A special splitter that gives priority to the backup split  
is preferred. These will sometimes be used for old answering machines  
where the handset can overuse the answering machine if it's picked up.

For the server end I was considering heartbeat plus dbrm. I might have  
to build my own box for that since I've seen it recommended you  
connect the two boxes by serial port as well as Ethernet.
