What does MTP do?

• A. Media Termination Point—controls media routing.
• B. Media Transmission Protocol—relays voice data.
• C. Media Timeslot Processor—schedules media streams.
• D. Media Termination Point—anchors media for certain signaling/media features.

Answer: (D)

MTP stands for Media Termination Point. Its job is to terminate the media path (RTP) and provide a stable point in the media plane where signaling and media features can be applied. This is why it’s described as anchoring media for certain signaling/media features—having a fixed media anchor lets features like hold, transfer, and conferencing work reliably, even if endpoints negotiate different codecs or need transcoding. It isn’t simply about routing media or relaying voice data, and it isn’t about scheduling media streams. Those functions describe other parts of the system, while the MTP specifically terminates and stabilizes the media path to support advanced signaling and media features.
