Hi Freinds, Has anyone done configuring the presence module only with DB. In my requirement, I am going to have multiple servers and share the same DB for presence info and enable Publish/Unpublish and Subscribe/UnSubscribe for all the clients who will be connecting to different Kamailio servers. Also expecting the NOTIFY to happen without any issues. I tried to get this done with modparam("presence", "subs_db_mode", 3) But failed. Please guide me for this. Best Regards, Roy.
