It needed some parameter tweaks in the cluster configuration to perform 
reasonable, but once optimized, it does its job very well, especially in 
terms of performance and availability.

For me the second solution seems to be easier to maintain and to 
troubleshoot, because each node works on the same data, and no routing 
between different proxy pairs has to be performed for on-net calls.

But again, I think it's more a matter of taste than a matter of which 
works better than the other.
