In this section:

The SBC Core supports the relaying TCP traffic (in addition to SIP/SDP traffic) with the use of a Relay Profile object and a Relay Port configuration on a per-Zone basis.

The Relay Port is used to establish end-to-end TCP relay connections between the TCP endpoints and the servers. the SBC terminates the connections initiated by the device and initiates connections towards the respective servers. TCP traffic policing and routing are performed based on the SBC local IP and port on which the connection is terminated. TCP packets are relayed with any content, for example, HTTP, XCAP, XMPP, or USS.

Up to 512 Relay Ports are configurable per zone, and up to 1000 system-wide.

Refer to Relay Profile - CLI for Relay Profile configuration details.
