Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 61

A company deploys centralized Cisco UCM architecture for a hub location and two remote sites.
✑ The company has only one ITSP connection at the hub location, and ITSP supports only G.711 calls.
✑ Remote site A has a 1-Gbps fiber connection to the hub location and calls to and from remote site A use G.711 codec.
✑ Remote site B has a 1-T1 connection to the hub location and calls to and from remote site B use G.729 codec.
Based on the provided guidance, a Cisco voice engineer must design media resource management for the customer. What is the method that needs to be followed?

Answer options

• A. configure the hardware transcoder on the site B router
• B. configure the hardware transcoder on the site A router
• C. configure the hardware transcoder on the hub location router
• D. configure the software transcoder on Cisco UCM to support voice calls to and from both remote sites

Correct answer: C

Explanation

The correct answer is C because the hardware transcoder needs to be placed at the hub location to facilitate the conversion between the G.711 and G.729 codecs for calls coming from remote site B. Options A and B are incorrect as the transcoder should not be at the remote sites, and option D is wrong because it suggests using a software solution, which does not address the need for hardware transcoding specifically at the hub.
