When Brilo AI is unsure, the Brilo AI voice agent follows configured fallback behavior: it attempts a short clarification (clarifying question), applies a confidence threshold to decide whether to continue, and then performs a fallback action such as a warm transfer with context, a cold transfer, voicemail, or decline. Admins configure these steps so uncertain calls either resolve with the agent or escalate to humans with preserved context and a post-call summary. This behavior reduces repeated questions for callers and keeps human agents focused on cases that require judgment.

What if the agent is uncertain? — The agent asks one short clarifying question and, if still unsure, follows your fallback rules.

What happens when confidence is low? — Brilo AI compares intent confidence to your configured confidence threshold and then clarifies, retries, or escalates.

Can the system escalate? — Yes; Brilo AI can escalate with context using warm transfers or cold transfers depending on your routing rules.

Enterprise buyers ask “What happens when the AI is unsure?” because uncertain or low-confidence interactions increase caller friction and risk incorrect actions in regulated sectors like healthcare and banking. Buyers need predictable escalation, clear audit trails, and control over when the Brilo AI voice agent can act versus when it must hand off. Decision-makers want to know how Brilo AI preserves caller context, minimizes repeats, and keeps agents productive while meeting internal safety policies.

When uncertainty occurs, Brilo AI runs a short, deterministic workflow: detect intent, check a confidence score, try a single clarifying prompt, then follow the configured fallback path. Administrators set routing rules and a Phonebook so fallback destinations receive either the raw audio plus transcript or a structured post-call summary. Brilo AI uses intent detection and session limits to avoid unbounded context drift.

In Brilo AI, confidence threshold is a numeric policy setting used to decide whether a detected intent is reliable enough to act on.

In Brilo AI, clarifying question is a short follow-up prompt the agent uses to disambiguate caller intent before escalation.

Brilo AI enforces guardrails to prevent unsafe or unpredictable behavior. Typical guardrails include hard limits on session persistence, explicit denial of high-risk operations without human authorization, and thresholds that force escalation when intent confidence is low. Agents should not guess or fabricate answers when below the confidence threshold; instead, Brilo AI must clarify or escalate.

In Brilo AI, fallback action is the configured outcome (transfer, voicemail, decline) executed when clarification does not yield sufficient confidence.

Healthcare: A patient calls to change a medication refill. The Brilo AI voice agent asks a single clarifying question to confirm which medication is meant. If the caller’s answers are ambiguous or contain protected health information that requires verification, Brilo AI follows your fallback rules and routes the call to a nurse or care coordinator with a transcript and summary.

Banking / Financial services / Insurance: A caller requests a wire transfer but uses ambiguous phrasing. The Brilo AI voice agent applies the confidence threshold; if the request remains unclear, the system performs a warm transfer with context so the relationship manager sees the intent, transcript, and any captured entities. For suspicious or high-value requests, Brilo AI defers to human authorization according to your policy.

Brilo AI supports smooth handoffs. When a handoff is triggered, the system can perform:

Brilo AI maintains a short conversation history and post-call summary so human agents do not need callers to repeat critical information. Handoffs are driven by your admin-defined routing rules and Phonebook destinations.

When configured, Brilo AI reduces repeated questioning, preserves context for human agents, and routes borderline or risky calls to the right person. The result is fewer escalations for routine issues, faster resolution for complex cases, and clearer handoffs that lower agent effort and caller frustration. Outcomes depend on your configuration of confidence thresholds, fallback destinations, and integration with agent workflows.

How many clarifying questions will Brilo AI ask?

Brilo AI follows your admin policy; typical setups ask one short clarifying question and then follow fallback rules if confidence remains below the configured threshold.

Will the agent ever act on low-confidence information?

No. Brilo AI uses the configured confidence threshold to prevent actions on unreliable intent detection; below that threshold the agent clarifies or escalates per your routing rules.

Can Brilo AI preserve PII or medical context when handing off?

Brilo AI can include captured entities and a transcript in the handoff packet, but you must configure what fields are shared and ensure your integrations and internal policies meet your compliance requirements.

What if call audio quality prevents the agent from understanding?

If automatic speech recognition confidence is low due to poor audio, Brilo AI follows fallback behavior—clarify, retry, or route—rather than guessing.

How do I change the fallback destinations?

Update your Phonebook and routing rules in the Brilo admin console to change warm transfer targets, cold transfer numbers, or voicemail destinations. Test changes with ambiguous calls before full rollout.
