Software-Based Media Resource

D.

Sure, I can provide a detailed explanation of the answer to your question!

The Cisco IP Voice Media Streaming Application is a software-based application that runs on Cisco Unified Communications Manager (CUCM) and provides various media resources for IP telephony services. One of the media resources that can be provided by this application is a transcoder.

A transcoder is a software-based media resource that is used to transcode audio streams between different codecs. Codecs are used to compress and decompress audio signals for transmission over a network. However, different devices and systems may use different codecs, and when a call is made between devices using different codecs, a transcoding process is required to convert the audio signal from one codec to another.

The Cisco IP Voice Media Streaming Application can provide transcoding services for calls between different devices and systems, allowing them to communicate with each other using the appropriate codec. This can improve call quality and reduce bandwidth usage by using the most efficient codec for each call.

So, the correct answer to your question is C. transcoder. The other options listed are also types of media resources that can be provided by the Cisco IP Voice Media Streaming Application, but they are not specifically related to transcoding audio streams.

• A video conference bridge is a media resource that allows multiple participants to participate in a video conference call.
• An auto-attendant is a media resource that provides automated voice prompts and menus to callers, allowing them to navigate through a phone system to reach their desired destination.
• An annunciator is a media resource that provides prerecorded announcements or messages to callers, such as a message indicating that a call is being recorded.
