Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 344

An end user at a remote site is trying to initiate an Ad Hoc conference call to an end user at the main site. The conference bridge is configured to support G.711.
The remote user's phone only supports G.729. The remote end user receives an error message on the phone: `Cannot Complete Conference Call.` What is the cause of the issue?

Answer options

• A. A software conference bridge is not assigned
• B. The remote phone does not have the conference feature assigned
• C. A Media Termination Point is missing
• D. The transcoder resource is missing

Correct answer: D

Explanation

The correct answer is D because the G.711 and G.729 codecs are incompatible without a transcoder to convert between them. The other options are incorrect as they do not address the codec mismatch issue that prevents the conference call from being established.
