Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 66

An administrator is working on an issue between the customer's Cisco Unified Border Element and the service provider. The provider only wants to see mid-call signaling from the Cisco Unified Border Element for fax calls. Which command must be configured on Cisco Unified Border Element?

Answer options

• A. midcall-signaling passthru
• B. no update-callerid
• C. midcall-signaling passthru media-change
• D. midcall-signaling preserve-codec

Correct answer: C

Explanation

The correct command is 'midcall-signaling passthru media-change' because it allows mid-call signaling to be passed through during media changes specifically for fax calls. The other options do not meet the requirement of signaling for fax calls or are unrelated to mid-call signaling for this scenario.
