Hi Bogdan,

That's what I said:

"We'd like to put a keepalived in front of both OpenSIPS servers".
keepalived is VRRP.

My question is you'll still have just one keepalived server monitoring
the systems.

I'm trying to understand what others do here. We have for this customer:

DC1:

OpenSIPS <-> Asterisk...Asterisk...Asterisk


DC2:
OpenSIPS <-> Asterisk...Asterisk...Asterisk


What do others put in front to switch between the two datacenters but
still avoiding having one keepalived/heartbeat server inbetween these
two DCs?

Do you address this by having a few heartbeat/keepalived servers that
get returned for the DNS records, for example:

sip.mycustomer.com returns a keepalived IP that is running in each
datacentre whereby each VRRP server points to both DCs. Then if anyone
one goes down its points to the other?

Thanks,

Gavin.
