Everyone talks about how good their AI is. Nobody talks about what it won't do. We think that matters more. These aren't suggestions — they're hardcoded constraints that can't be overridden, negotiated, or prompt-injected away.

Technical Reliability
Never continue speaking over a customer who's trying to interrupt — barge-in detection must work
Never generate robotic or glitchy audio — if TTS fails, gracefully apologize and offer callback
Never repeat the same "I didn't catch that" verbatim — vary the phrasing
Never loop infinitely on failed transcription — after 3 attempts, offer transfer or callback
Never play audio at wrong speed or pitch — validate encoding before sending
Never let dead air exceed 3 seconds without acknowledgment
Never cut off mid-sentence due to latency spikes — complete the thought
Never play intro audio over customer who started speaking — detect early speech and skip
Never stack multiple filler sounds back-to-back
Never let background audio overpower speech
Never confirm calendar booking if API failed — offer callback to confirm
Never claim SMS was sent if sending returned error — verify number
Never proceed with appointment if time slot check failed — don't guess
Never lose lead data on API failure — queue for retry, persist locally first
Never expose technical error messages to caller
Never blame integrations to customer — own it as "brief issue"
Never timeout silently — keep customer informed during long processing
Never drop call on worker crash — ensure graceful degradation
Never lose conversation context on reconnection — session state must persist
Never create duplicate leads from same call — dedupe on phone + session
Never send duplicate SMS notifications — track send status
Never overwrite customer-provided info with stale data

Never mix up caller data between concurrent calls — session isolation required
Never persist PII longer than necessary — respect retention policies
Never log full phone numbers in plain text to public logs
Never store call recordings without explicit disclosure to caller

Never let memory/entity lookup slow down response — cache hot data
Never process messages sequentially if they can be parallelized

Why this matters for enterprise.
1
Compliance isn't optional
TCPA, state telecom laws, recording consent — one violation costs more than your annual AI budget. Every guardrail here maps to a real regulatory requirement.
2
Your brand is on the line
The AI represents your company. If it makes up prices, promises refunds, or gives medical advice — that's your liability. These guardrails protect your brand as much as your callers.
3
Technical reliability at scale
When you're pushing 50,000 calls a month, "it usually works" isn't good enough. Our technical guardrails ensure graceful degradation, data integrity, and zero dropped calls.
Trust isn't a feature. It's the foundation.
Every guardrail here is enforced in every call, for every customer. No exceptions.
