Red Flags in Voice Agent Spend
Voice agents bill per minute and per token — the red flags are about unbounded volume, not rates.
The red flags
1. No per-call ceiling — one call can run long and bill big.
2. Retry storms — failed calls re-bill minutes.
3. 24/7 autonomy — no time-of-day review window.
4. Mid-call tools ungoverned — purchases triggered inside calls.
5. No per-campaign budget.
The fix
Per-call ceilings, velocity limits on retries, and category rules separating minutes from tokens.
FAQ
