[Freeswitch-users] freeswitch distributed

I want to make freeswitch distributed in such a situation. Several offices in each of fs. We need a unified dialplan, a single entrance/exit on the SIP external gateways, in the case of unavailability of one of the fs others work without his participation. How to understand. It should be the following. Base presence to keep in a separate database (pgpoll + pg). Dialplan, configure pull xml_curl. What can you tell from the web-application (wikipbx, fs2web etc)? The main task of which will impact dialplan, configure, directory?
