[OpenSIPS-Users] need some help using opensips 3.0 cluster module .

[Liviu Chircu]

Sasmita,

Dialog replication is not meant to work on such a cluster. Since dialogs 
retain more
state than registration, they are more sensitive to the IP of the 
current node.

If you want high-availability for dialogs, the basic unit of deployment 
shifts from
1 server to 2 servers (an active/backup pair).  And in order to have the 
same IP on
both servers, you must use VRRP-capable software, such as keepalived.

Deploy as many pairs as needed in each location according to your 
traffic volume, and
make sure to give each pair its own Virtual (highly available) IP that 
can automatically
move from the active node to the backup in case the former one catches fire.

PS: this information should be included in the dialog replication blog 
post, so make
sure to read it closely.
