Calls to an Expressway cluster are routed to whichever

For connections to non-Expressway systems, the
Expressway uses a round-robin selection process to
decide which peer to contact if no resource usage
information is available.

Configuring Traversal Client Zones
To traverse a firewall, the Expressway must be connected with a traversal server (typically, an Expressway-E).
In this situation your local Expressway is a traversal client, so you create a connection with the traversal server by
creating a traversal client zone on your local Expressway. You then configure the client zone with details of the
corresponding zone on the traversal server. (The traversal server must also be configured with details of the
Expressway client zone.)
