Answer: B,D,E
Explanation:
Three MTP types can be configured:
-Software MTP: provided by the Cisco IP Voice Media Streaming App service on Cisco Unified Communications Manager:
—
This MTP type can convert G.711 mu-law to G.711 a-law and vice versa.
—
This MTP type can packetize conversion for a given codec; for example, when one call leg uses 20-ms sample size and the other call leg uses 30-ms sample size.
-Software MTP: configured on Cisco IOS routers:
—
This MTP type does not require any DSP resources onthe Cisco router. Enable Cisco
IOS Software MTPs by using the maximum session software <n> command. As many as 500 software-based sessions can be configured. The codec and packetization of both call legs must be identical.
—
This MTP type typically is used for Resource Reservation Protocol (RSVP) agent configurations or Cisco Unified Border Element media flow-through configurations.
—
Cisco Unified Communications Manager does not differentiate between software-and hardware-based Cisco IOS MTP configurations. Every Cisco IOS Software MTP is considered as a hardware MTP in Cisco Unified Communications Manager.
