Which Cisco Unified Border Element configuration is used in Contact Center Enterprise with Cisco Unified Customer Voice Portal and Cisco Unified Border Element deployment?

Question

Options

• Avoice gateway must be dedicated for VXML browser sessions.
• BCisco Unified Border Element must be configured as media pass flow-around mode.
• CCisco Unified Border Element must be configured as media pass flow-through mode.

Explanation

In a CCE + CVP + CUBE deployment, the voice gateway running the VXML browser must be dedicated to that role because VXML browser sessions require specific IOS services (media processing, ASR/TTS integration, VXML application state management) that conflict with other gateway functions - sharing the gateway degrades call quality and causes resource contention.

Why the distractors are wrong:

• B (flow-around): Media flow-around bypasses CUBE for the media path, which breaks CVP's ability to properly anchor and process media during VXML interactions.
• C (flow-through): While flow-through is a valid CUBE media mode in other contexts, it is not the defining architectural requirement for this specific CCE/CVP/CUBE deployment - it describes how media traverses CUBE, not what the gateway role must be.
• D (Box-to-box CUBE): Box-to-box (BoB) CUBE is a high-availability feature for redundancy, not a baseline deployment configuration requirement.

Memory tip: Think "VXML = Dedicated" - VXML browser sessions are resource-intensive interactive voice applications that need a gateway all to themselves, just like a dedicated server for a demanding workload. If a gateway is sharing duties, VXML suffers.
