How voice is billed
Voice is billed the same way as everything else on Alfe: usage draws down your tenant’s single, shared USD credit pool. There’s no separate voice invoice and no per-provider bill to reconcile — voice, model usage, compute, channels, and storage all come out of the same balance. See core concepts for how the pool works.
What draws on the pool
Section titled “What draws on the pool”- Text-to-speech. Turning an agent’s words into audio is metered by the amount of text spoken.
- Speech-to-text. Transcribing what a caller says.
- Phone numbers. A number carries a recurring monthly charge, plus per-minute charges for calls and per-message charges for texts and WhatsApp. See Phone & SMS.
You don’t pre-buy voice separately or manage a voice-specific balance — as an agent talks, listens, or takes a call, the cost is deducted from the shared pool.
Keeping the pool funded
Section titled “Keeping the pool funded”Voice usage is checked against your available balance. If the pool is empty, new voice usage is declined until it’s topped up — so keeping a balance (or enabling auto-recharge) keeps your agents reachable. You can manage your balance and auto-recharge from the dashboard.
