Hi Klaus,
We use DNS updates. We have special scripts based on sipsak (Thanks Nils!),
that check all SIP servers every minute. If something is wrong, then we
update our DNS dynamically to point to another SIP Server. If the UAs are
unable to register then they redo their DNS query and find the new IP.
Works quite well in combination with replication since the backup server has
the exact duplicate location table.
Regards,
Andres

Is it yet possible to build redundancy on top of SRV? I tested some
clients (Xlite, Budgetone-100, Windows Messenger 4.7) wether they use
SRV records to locate the proxy and Messenger is the only one who uses it.
So, if I use these clients, is there any other failover solution than IP
takeover?

klaus
