Now that you have configured the dial plan for inbound and outbound calls on the Expressway-E, you can turn your attention to the Expressway-C. Recall that you already have the Zone to UCM configured as well as three Zones for CMS, one for each individual server. You only need a rule to route calls that don't match the local Unified CM or CMS domains to the traversal zone so that it will reach the Expressway-E.
|Mode||Alias pattern match|
Note: Notice this is the same as the DNS zone on the Expressway-E.
|On successful match||
Note: Having this parameter set to Continue allows Expressway to keep searching for possible matches if there is a failure on this rule. We will show a use case for this later on when CMS is used to convert different SIP variants.
Finally, we need to verify that TURN is configured and place a test call.
