Oracle Communications Session Border Controller — Question 8

The Session Border Controller is not routing calls to a specific SIP endpoint from the backbone realm to the access realm in an Access-Backbone architecture.
How can you troubleshoot this routing issue?

Answer options

• A. by running the notify berpd force command
• B. by running the show sipd endpoint-ip <phone number> command
• C. by checking the sip-manipulation configuration element used for routing from the backbone realm to the access realm
• D. by checking the registration-cache configuration element used for routing from the access realm to the backbone realm
• E. by checking the local-policy configuration element used for routing from the access realm to the backbone realm

Correct answer: D

Explanation

The correct answer is D because the registration-cache configuration element is critical for managing how calls are routed from the access realm to the backbone realm, which can influence the overall routing process. Options A and B do not directly address the routing issue, while options C and E focus on configurations relevant to the opposite direction of call routing, making them less applicable in this scenario.
