In the text below I quote Kerker 'SER does support DNS failover.'.
Is this ser or openser? Where can I read more about this?

Now, if I disable one of the Gateways, I hang every second

try the second A record address if the first doesn't answer.
How can I solve
this? Shouldn't OpenSER fail over to the second A record listed
in the NAPTR
=> SRV
resolving? Or will OpenSER continue to resend all SIP INVITES
until timers
fire? Would
it help if the proxy recieved an ICMP port/destination
unreachable from the
network? Is
there anyway to get around this? In the other direction, from
POTS to sip,
the PGW2200
nicely switches over to the second of my two OpenSER servers if
I shut one of
them down. These servers have the same DNS entries (but for
another SIP domain, NAPTR =>
SRV => 2x A record).
Yes, OpenSER or for that matter every transaction stateful proxy
should
do RFC 3263 based fail-over. But as you can imagine this is pretty
complex to implement and that's why openser does not support it
yet, it
is listed on the development roadmap. The newest release of SER
does
support DNS failover.
