[OpenSIPS-Users] Dialog module - profile replication not working

Hi, John!

First of all, this is a known issue [1] with the 2.2 clusterer, where 
you cannot use both replication mechanisms of dialog concurrently. This 
has been fixed in 2.3 and above, and required a significant code 
refactoring, which is unlikely to get backported soon.

Secondly, what you are trying to do is unlikely to solve your problem 
even with 2.3+, as the dialog replication mechanism __already__ 
broadcasts the profiles of each box throughout its cluster. 
Consequently, reusing the same cluster id to share the profiles between 
boxes (yet again) will effectively double the value of each profile. If 
I correctly understand your intention, simply enabling dialog 
replication (profile included) will solve your problem. Please correct 
me if I'm wrong.

The documentation could use some improvements in order to reflect the 
following (I will take care of this):

     * dialog replication allows you to have "hot backups". Profiles are 
included. Recommended cluster size: 2

     * profile replication is meant to be used in 
active-active-...-active setups, in order to easily achieve whatever 
platform-wide limitations you may think of. The OpenSIPS cluster size 
can grow indefinitely here.

Some food for thought: currently in OpenSIPS 2.3+, although merging the 
above two concepts will work, the profiles are likely to be counted more 
than once, and your limits will hit faster. The clusterer needs more 
love in order to support "profile sharing between highly available
