Most AI receptionists rent a black box. CoveCall runs its own realtime voice engine — every millisecond from “hello” to answer is ours to tune, and it shows.
Twilio streams the caller's audio to our engine in 20-millisecond frames. From there, everything is ours.
Our own voice-activity detection locks onto the caller — not the TV behind them, not a cough, not a passing conversation — and knows when they're actually done talking.
Whisper runs inside the engine itself — no extra network hop — turning an utterance into text in a few hundred milliseconds.
The model routes every turn through an allow-listed toolset: check availability, book, notify, transfer, take a message. Output is guarded before a word is spoken.
Slow turn? Neuros covers it like a person would — “let me pull up the calendar…” — with pre-rendered, context-matched fillers.
Phones are unforgiving. The engine assumes providers hiccup, deploys happen mid-call, and callers mumble — and handles all three.
TTS down? A pre-rendered apology plays. Deploy mid-call? The call says goodbye, finalizes, and your transcript still lands. No caller is ever left in silence.
Slots come from live calendar free-busy inside your opening hours; conflicting times are refused; nothing is confirmed to a caller unless it verifiably happened.
Per-call and per-plan minute budgets are enforced at the webhook and inside the engine, so usage can never run away from you.
Every call streams to your dashboard in real time — transcript, tool calls, and a take-over button that bridges you in mid-call.
Telephony webhooks are signature-verified and media sessions carry short-lived signed tokens — forged traffic is dropped at the door.
Caller speech is fenced as untrusted data with input screens and output guards. Attempts are deflected in character and flagged.
Row-level security keeps every business's data its own; your assistant answers only from your records.
Postgres, a long-lived engine, and a CDN'd app — monitored health checks, metered usage, no exotic moving parts.
