What is the purpose of a media gateway in relation to a TSC?

The media gateway plays a crucial role in the communication process managed by a Tactical Session Controller (TSC) by converting media streams between different formats and protocols. This function is essential because different devices and networks often use various encoding methods and transmission protocols for audio and video data. The media gateway facilitates seamless communication by ensuring that these different formats can work together, enabling interoperability between disparate systems and networks.

This conversion allows for voice, video, and other media to be effectively transmitted across different platforms, which is especially significant in environments where legacy systems might exist alongside newer technologies. By handling the challenges of format compatibility, the media gateway ensures that the overall session management process is efficient and effective, enabling high-quality communication.

The other options do not accurately capture the primary role of a media gateway in relation to a TSC. While security, session initiation, and call recording are important aspects of session management, they do not represent the core functionality of the media gateway, which is fundamentally focused on media stream conversion.
