Logic would suggest that SIP-only failover is highly desirable, as it
is orders of magnitude easier to implement.
As I mentioned, this is harder to do with B2BUAs, which need
session/dialog/transaction endpoint state. Proxies, on the other
hand, do not keep state machines for the former two, and thus are a
relatively thin interoperability layer from a state perspective.

The original question was about a HA SIP load-balancing. No mention
of RTP was made.
