Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 88

Calls are not working when sent from a Cisco Unified Border Element to a service provider. After investigating the logs, the engineer notes that the Cisco Unified Border Element is sending the extension only. How is the issue addressed in the configuration?

Answer options

• A. voice class request sip-header diversion
• B. sip-header contact modify
• C. voice class request sip-header modify
• D. request invite sip-header diversion modify

Correct answer: D

Explanation

The correct answer is D because modifying the SIP header for the INVITE request is essential to ensure that the complete information is sent to the service provider. The other options do not specifically address the need to modify the INVITE request for proper call handling.
