Note: Systems that are configured as peers must not also be configured as neighbors to each other, and vice

Neighboring your clusters
To neighbor your local Expressway (or Expressway cluster) to a remote Expressway cluster, you create a
single zone to represent the cluster and configure it with the details of all the peers in that cluster:
single zone to represent the cluster and configure it with the details of all the peers in that cluster:
1. On your local Expressway (or, if the local Expressway is a cluster, on the master peer), create a zone of
the appropriate type. This zone will represent the connection to the cluster.
2. In the Location section, enter the IP address or FQDN of each peer in the remote cluster in the Peer 1 to
Peer 6 address fields.
Note that:
n
Ideally you should use IP addresses in these fields. If you use FQDNs instead, each FQDN must be
different and must resolve to a single IP address for each peer.

The order in which the peers in the remote Expressway cluster are listed here does not matter.

Whenever you add an extra Expressway to a cluster (to increase capacity or improve redundancy, for
example) you will need to modify any Expressways which neighbor to that cluster to let them know about
the new cluster peer.

Task 8: Configuring traversal zone search rules
To create the search rules to route calls via the traversal zone.
1. Go to
Configuration > Dial plan > Search rules
