If you’re still in the planning stage, there’s a lot more to think about.  Your Asterisk failure detection will be very simplistic (is the process dead).  Synchronization of data – without risking synchronization of corrupt data to a peer.  Prevent a deteriorating/failing peer corruption from corrupted the other peer (i.e. now shared resources).  Awareness of upstream (e.g.: route/network) failures making the peer unavailable – and how to detect that.  Etc. etc.


Here’s a good checklist of things to consider in your design:  http://www.voip-info.org/wiki/view/Asterisk+High+Availability+Design


If you are building a small/home office HA then the free version of commercial tools may be the way to go.  If have a $0 budget but for a larger installation, use the design guide above to help figure out which compromises to make.  (Heartbeat / Linux HA is better than nothing).
