Hi Christoph,
We are currently using a combination of the following mechanisms to provide HA (and these have been accepted by several carriers):
1) We do DNS based failover between locations according to RFC3263 (Locating SIP-Servers). E.g. if a server or datacenter goes down, the I-CSCF would re-route the traffic to the other server or datacenter 2) We run the S-CSCF as Active/Passive Node, where we restart Kamailio on the Passive node in case of single-node failure.
Nothing spectacular I guess, but it works for us.
Thanks, Carsten

Hi Carsten,
that Kamailio's S-CSCF-Usrloc does not support DB-Realtime like the "usual" usrloc module does.
Just being curious: If high availability is not supported this way by the S-CSCF-Usrloc, then what is your plan how to support high availability?
Thanks for any hints, Christoph
