I understand from the documens that, in order to enable users outside the firewall to communicate with internal users, an Edge Server must be deployed.
But, in a scenario where the company HQ with internal OCS deployment is connected via WAN with a remote branch office, it is mandatory to deploy a second OCS server only for the local branch users ? Is the RTP traffic routed locally between peers in the local network, or it is routed passing through the remote HQ OCS server as the signaling traffic ?
Any response would be appreciated.
