[SR-Users] dns failover and branches

[Juha Heinanen]

If Request-URI hostpart is a domain name with more than one SRV record,
it appears that each SRV destination creates its own Kamailio branch.
If branch route is set before t_relay(), it is executed only on the
first SRV destination.  If the first SRV destination fails, Kamailio
tries automatically the second one, but any branch flags set in the
branch route are lost.

What is the simplest way to make Kamailio preserve the stuff set in the
branch route for all SRV destinations?
