RTP Media Flow
The following diagram shows the media flows and typical port usage on the VCS Expressway and VCS Control. The
TURN server on the VCS Expressway relays the media between the Jabber Guest client and the B2BUA on the VCS
Control, and the media also flows between the B2BUA and the internal endpoint.

Jabber Guest Licensing and Call Capacity
The VCS licensing requirements for Jabber Guest sessions are as follows:
■
Each session typically uses 4 TURN server relays on the VCS Expressway.
■
2 traversal call licenses are required per Cisco Jabber Guest session:
—
1 traversal call license on the VCS Expressway for each Cisco Jabber Guest session
—
1 traversal call license on the VCS Control for each Cisco Jabber Guest session
The maximum number of Jabber Guest sessions that can be supported through the VCS depends on the type of
, and whether they are deployed as a single VCS Control and VCS Expressway pair, or as a pair
of clusters.
