MySQL replication can potentially be a lighter-weight solution to the 
NBD ("cluster") layer, but that too isn't particularly seamless.

I would have to disagree with your assessment about Linux-HA, but it 
really depends on the precise nature of the expectation and requirement. 
  Nevertheless, we have deployed many OpenSER/Kamailio systems in 
high-volume production environments and it has proven adequate for such 
purposes.
