Which two describe how media resources and audio streams operate with Cisco Unified Communications Manager? (Choose two.)

Question

Options

• AAudio streams are terminated differently depending on the signaling protocol, such as SCCP or
• BAudio streams are always terminated by media resources.
• CAll media resources register with Cisco Unified Communications Manager.
• DThere are no situations in which IP phone-to-IP phone audio streams will go directly between
• ESignaling between Cisco Unified Communications Manager and hardware media resources uses

• A
  17% (8)
• B
  71% (34)
• D
  4% (2)
• E
  8% (4)

Explanation

In CUCM's media resource architecture: (B) audio streams are always terminated by media resources when a media resource is involved in the call-for example, conferencing, transcoding, or MOH always flow through a media resource rather than directly between endpoints; and (C) all media resources (hardware conference bridges, transcoders, MTP devices) register with CUCM so that CUCM can allocate and manage them. Option A is incorrect because audio termination does not depend on whether signaling uses SCCP or SIP. Option D is incorrect because IP phone-to-IP phone calls can and do stream audio directly (G.711 same-region calls). Option E is a distractor about signaling mechanics.
