Oracle Communications Session Border Controller — Question 31

After configuring Header Manipulation Rules (HMRs) for topology hiding, your subsequent testing shows that the manipulation is not taking effect.
Identify two causes for this (Choose two.)

Answer options

• A. You have not configured the out-manipulationid parameter of the sip-interface configuration element.
• B. You have not enabled policy-based realm-bridging.
• C. The value of the name parameter in the header-rule configuration element is different than the value of the out-manipulationid parameter in the sip-interface configuration element.
• D. The value of the match-val-type parameter is not written correctly.
• E. The home-proxy-address value does not match the $LOCAL_IP value in the new-value parameter.

Correct answer: A, E

Explanation

The correct answer includes A because the out-manipulationid must be configured for HMRs to function properly. E is also correct since the home-proxy-address needs to match the $LOCAL_IP for the new-value parameter to be effective. The other options do not directly relate to the issues with header manipulation taking effect.
