I think the sip server implementations are pretty good here. Besides 
that, for client interaction it is required only DNS server 
configuration, nothing in sip server.

What I meant is the headache for sip server providers to deploy two 
different fault tolerant solution:
- one based on DNS
- one based on shared/virtual IP or load balancer

Each of them will require maintenance, man power, etc... Anyway, even 
with second option, good DNS in phones does not harm.

Cheers,
Daniel
