Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 86

An incoming off-net call to a user fails. An engineer notices that the off-net call is G.711, but the phone accepts only G.729. Which media resource on a Cisco
Unified Border Element and Cisco Unified Communications Manager must the engineer configure to manage the codec negotiation?

Answer options

• A. transcoder
• B. CFB
• C. MOH
• D. MTP

Correct answer: A

Explanation

The transcoder is the correct answer because it can convert audio streams between different codecs, such as G.711 to G.729. The other options, CFB (Call Forward Busy), MOH (Music on Hold), and MTP (Media Termination Point), do not perform codec transcoding and are not suitable for managing codec negotiation.
