You can achieve the active-passive setup using Linux HA techniques using heartbeat and the like. You can also do load-balancing with LVS. What I am not sure about is maintainance of call and session states between the two servers such that when one server dies, the other server picks its IP addresss, it keeps the calls in progress, up. There might be ways of sharing call states using Asterisk Manager interface where each server intermittently logs into the other to share their data OR if this info is temporarily stored in the astdb then maybe you can share the same astdb between the two servers. I am not sure about (*) internals enough :( But this should give you some ideas, I hope. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com --
