Yes, doing "high availability" in a way that allows switching between servers to be transparent is difficult. See http://sipxecs.sipfoundry.org/rep/sipXecs/main/sipXregistry/doc/SyncDesign.{txt,html} for what it took in sipX. > Sincerelly I think that it would be more feasible to create a solution > based on IP failover. I do know this is not so cool as a SIP DNS > failover mechanims but... IP failover would give you the ability to ensure that all REGISTERs at a given time go to one server. But immediately after switching servers, the new server would have no registrations in its database (as the registrations would have expired).
