Hi Klaus,

Ok, so I will try another setup:
2 proxies, each of them interacts with a separate mysql database.
Registrations will be replicated between the proxies using t_replicate.
I have also seen a replication parameter in serweb when adding new
contacts via the web interface and the FIFO. I found no documentation
about it, but I guess this will also replicate the new contact to
another sip proxy (don't know if its implemented yet).
So, both proxies can be used for registration and normal proxy tasks.
But how can a proxy catch up the lost REGISTER messages from the other
proxy during a "down" period?
I think, one possibility would be, that when the proxy/database is "up"
again, the database begins to mirror the complete state from the other
database, and only when this is finished, ser will be started again and
reads the current user location from the database.
Is there another, maybe simpler solution to this problem?
there will be a new module availble for our customers shortly which handles
the replication of registers much more intelligent.
It stores the missed Register from the "down" period and updates the recovered
server with informations which are required by this server to be up-to-date
again.

I have found the db_mode option in the userloc module,
which controls
updates in the location table. But how are the
lookups
handled in ser?
If a user location will be requested by
lookup("location"),
will this query
the backend database or only the RAM. Is this
lookup behaviour also
configurable (how?)?
No, it will not query the database, only memory will be used.
I'm thinking about a configuration with 2 ser
proxies and
one database
backend. If the lookup only queries the cached
location
table, I would have
to froward the registrations between the two
proxies via
t_replicate. But
wouldn't this cause both proxies to update
the database
resulting in two
entries in the location table for each
registration?
Yes, this is not possible at the moment. Another database mode which
will query the backend database when doing lookups is on
our todo list.
