Which three of these are characteristics of a Cisco Unified Communications Manager softwarebased Media Termination Point? (Choose three.)
A.
The codec and packetization of both call legs must be identical.
B.
This Media Termination Point type does not require any DSP resources on the Cisco router.
C.
DSP resources are required.
D.
It can provide G.711 mu-law to G.711 a-law conversion and vice versa.
E.
It can provide packetization conversion for a given codec (for example, if one call leg is using a
20-ms sample size, but the other call leg is using a 30-ms sample size).
F.
This Media Termination Point type is typically used for RSVP agent configurations or Cisco
Unified Border
Element media flow-through configurations.
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.
