In a Cisco Unified Contact Center Enterprise deployment, callers report intermittent voice-quality issues. What might cause this problem?

Question

Options

• AThe Cisco voice gateways have too few trunks to accept the inbound calls.
• BThe Cisco Finesse is locking up because of a virus.
• CThe system has too few DSP transcoding resources to support all the calls across the WAN.
• DCisco Unified Communications Manager has too few conference bridge resources.
• EA different voice codec is used by the caller and the agent.

• A
  24% (4)
• B
  12% (2)
• C
  59% (10)
• D
  6% (1)

Explanation

DSP transcoding resources are the bridge that converts between different voice codecs when calls traverse a WAN. When insufficient DSP resources are available, the system cannot transcode all simultaneous calls cleanly, causing packets to be dropped or delayed intermittently - exactly the symptom described.

Why the distractors are wrong:

• A - Too few trunks would cause calls to be rejected or busy, not degrade voice quality mid-call.
• B - Cisco Finesse is the agent desktop application; a virus affecting it would cause UI/login issues, not voice quality problems.
• D - Conference bridge resources only matter when calls are in a conference (3+ parties); a standard two-party call wouldn't be affected.
• E - This is a tempting trap. A codec mismatch is exactly why transcoding is needed - but the question says the system has DSP resources, just too few. Option E describes the condition that requires transcoding, while C describes what happens when you don't have enough of it to handle all calls simultaneously.

Memory tip: Think of DSP transcoders as "language interpreters" - if you have a conference room with 100 foreign-language speakers but only 5 interpreters, most conversations will be garbled or interrupted. Too few interpreters = intermittent quality problems, not a busy signal.
