Branch Survivability

Hi together,

where can I find information about Branch Survivability?

As far as I know the SAP CCtr needs DB connection for call routing. But in a branch where we only have a MediaRoutingServer (MRS) and a Mediagateway for PSTN Connection - what will happen if the WAN connection to SAP CCtr central site is down?

I need to ensure that in case of a WAN disconnect the branch office users can receive local incoming calls and can call out locally.

Thanks,

Robert
