Media and QoS

Endpoint A is attempting to call endpoint B. Endpoint A supports only G.711ulaw with a packetization rate of 20 ms, while endpoint B supports G.711ulaw with a packetization rate of 30 ms. Which two media resources are allocated to normalize packetization rates through transrating?

Choose two
  • A software transcoder on Cisco UCM
  • B hardware transcoder on Cisco IOS Software
  • C software MTP on Cisco IOS Software
  • D software MTP on Cisco UCM
  • E hardware MTP on Cisco IOS Software
Explanation

Transrating changes packetization time while retaining the same codec. For G.711 media legs with different packetization times, Cisco requires DSP-based hardware processing: a hardware MTP performs the repacketization, and a hardware transcoder can provide MTP functionality. Software MTP resources do not perform DSP-required repacketization.
