An engineer must enable the communication between two separate Expressway-C servers to allow inbound and outbound calling between different endpoints registered on each server. Which configuration…

Question

Options

• AConfigure a traversal zone on each server with a destination of the other Expressway-C.
• BConfigure a neighbor zone on each server with a destination of the other Expressway-C.
• CConfigure a transform on each server to strip the port numbers at the end of the alias.
• DConfigure a transform on each server to convert the calling alias into the called alias.

Explanation

To enable direct calling between endpoints registered on two separate Expressway-C servers (both internal, no firewall traversal involved), a neighbor zone is the correct configuration. Neighbor zones are used to link two Expressway peers at the same trust level on the same network, enabling them to forward calls to each other. A traversal zone is specifically for firewall traversal scenarios between an Expressway-C and Expressway-E pair, not between two Expressway-C servers. Transforms (choices C and D) manipulate aliases but do not establish the zone relationship needed for call routing between the servers.
