Re: [OpenSIPStack] High availability?

Yes, we have all of them in production already, so I am very familiar with HA SBCs.

The "heartbeat" part of HA is easy as you can just use the existing Linux HA code (http://linux-ha.org/)  The hard part would be writing a state mirroring protocol into opensbc - you need some mechanism to ensure that both servers know about every call in progress so that when they "swap" on a failure the second server doesn't reject the calls.
