[SR-Users] Guidance on using Kamailio as Presence Server and Scalability issues for millions of subsribers

[Thomas Hoffman]

We're trying to determine how best to design/architect a solution where we use Kamailio as a Presence/XCAP server and be scalable to support millions of subscribers.
I see the Dispatcher module, but it appears that requires having dedicated instances of the server running just in Dispatcher mode - then you can load balance across the actual instances of the presence servers. It's not clear if a server can be configured to work as a dispatcher and a presence server at the same time.

Does anyone have any high-level guidance how to approach this problem?

Thank you,

Tom Hoffman
