Media relay sets

Media relays are in charge of bridging RTP traffic of established calls. Like the Application Servers, they can scale horizontally as much as required.

Media relays are organized in groups so they can be assigned to a client/provider. Each element of the group has a metric that allows non-equal load balancing within the same group (i.e. media-relay1 metric 1; media-relay2 metric 2: the second media relay will handle two times the calls than the first one).

Hint

The static assignment of media relay groups is not the common practice but allow us to assign strategic resources to clients that need a warranted service. The most common usage of this groups of media relays is to place them near the geographic area of the client (usually far from the rest of the platform systems) in order to reduce latencies in their conversations.

In a standalone installation, only one media relay group will exist. By default this group only has a media server.

Note

The address displayed is the control socket, not the SDP address that will be included during SIP negotiation. By default this alone media-relay will share the same IP address that the User’s SIP proxy.
