Designing Media Resource Management for Cisco UCM Architecture
Question
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?

A. B. C. D.A.
In this scenario, the company has a centralized Cisco Unified Communications Manager (UCM) deployment with one ITSP connection at the hub location and two remote sites. The ITSP supports only G.711 calls, and remote site A uses G.711 codec, while remote site B uses G.729 codec.
Since the ITSP supports only G.711 calls, any calls that use a different codec (such as G.729) must be transcoded to G.711 at the site where the call enters or leaves the centralized Cisco UCM deployment.
Hardware transcoders can be used to convert the codecs in real-time, but they are expensive and require dedicated hardware. A better option is to use software transcoders, which can run on the Cisco UCM servers and use the available processing power.
Therefore, the best method for the Cisco voice engineer to design media resource management for the customer is to configure the software transcoder on Cisco UCM to support voice calls to and from both remote sites. This will enable the Cisco UCM to convert the codecs as necessary, ensuring that all calls are using the same codec (G.711 in this case) and avoiding any degradation in call quality.
Therefore, the correct answer is D. configure the software transcoder on Cisco UCM to support voice calls to and from both remote sites.
