Dialog replication is not meant to work on such a cluster. Since dialogs <br>
retain more<br>
state than registration, they are more sensitive to the IP of the <br>
current node.<br>
<br>
If you want high-availability for dialogs, the basic unit of deployment <br>
shifts from<br>
1 server to 2 servers (an active/backup pair). And in order to have the <br>
same IP on<br>
both servers, you must use VRRP-capable software, such as keepalived.<br>
<br>
Deploy as many pairs as needed in each location according to your <br>
traffic volume, and<br>
make sure to give each pair its own Virtual (highly available) IP that <br>
can automatically<br>
move from the active node to the backup in case the former one catches fire.<br>
<br>
PS: this information should be included in the dialog replication blog <br>
post, so make<br>
sure to read it closely.<br>
