In a Cisco Unified Contact Center Enterprise that is deployed in a multisite centralized model, which resource can be used for transcoding?

Question

Options

• ACisco Unified IP phone built-in-bridge
• BCisco Unified IP IVR CTI ports
• CCisco Unified Communications Manager CTI route points
• DCisco Unified Communications Manager software conference bridge resources

• A
  71% (42)
• B
  14% (8)
• C
  5% (3)
• D
  10% (6)

Explanation

In a multisite centralized UCCE deployment, remote sites use G.729 over the WAN to conserve bandwidth, but the contact center's central resources often require G.711 - the IP phone's built-in bridge (BIB) provides hardware transcoding capability directly at the remote site, performing codec conversion without requiring a separate dedicated DSP resource or hauling media across the WAN a second time.

Why the distractors are wrong:

• B (IP IVR CTI ports): CTI ports are software endpoints used for IVR call signaling and media termination, not codec transcoding.
• C (CTI route points): These are virtual routing objects in CUCM - they handle call routing logic, not media processing of any kind.
• D (Software conference bridge): Software conference bridges mix audio streams for multi-party calls but are not transcoding resources; they require all parties to use a compatible codec.

Memory tip: Think of the phone as a "Swiss Army knife" - the built-in bridge is the hidden tool already on-site at the remote branch, ready to convert codecs without shipping traffic back to headquarters. When you see "multisite centralized + transcoding," the answer lives at the phone, not at the center.
