Question 2

Refer to the exhibit.Calls to locally registered endpoints are failing. At present, there are two endpoints registered locally to this Expressway. An H.323 endpoint with an alias of “EndpointA” is registered, and a SIP endpoint with an alias of “EndpointB@pod1.local” is also registered. How is this issue resolved?

A : The dialplan must be redesigned to use the transforms to convert the alias into SIP URI format and then use separate search rules for each format that needs to be dialed within the local zone.

B : The calls are failing because there are insufficient licenses. Additional licenses must be installed for the Expressway to route these calls.

C : The current search rule does not match the call, so the search rule must be modified to include a SIP Variant of “Standards-Based”.
