Ultravox plans & pricing
| Plan | Monthly | Annual | Billing | Notes | Source |
|---|---|---|---|---|---|
| Pay as You Go | $0 | — | Per minute | No platform fee: first 30 minutes free as a one-time allowance, then $0.05/min, capped at 5 concurrent calls. SIP telephony adds $0.005/min. Text and thread usage is metered on this tier too, at $2.00 per 1M input tokens (uncached) and $15.00 per 1M output tokens. Unlimited playground access and an explicit no-surge-pricing guarantee. The 5-call concurrency ceiling, not the rate, is what forces an upgrade. | ultravox.ai |
| Pro | $100 | — | Hybrid | $100/month platform fee buys unlimited concurrency, an outbound call scheduler, 5 custom voices and 20 RAG corpora. Beyond the first 30 free minutes, usage still bills at $0.05/min on top of the fee, with SIP at the slightly lower $0.0048/min. Text and thread usage metered at $2.00 per 1M input tokens (uncached) and $15.00 per 1M output tokens. The page offers the first 30 minutes free, and the Pro card includes everything in Pay As You Go, which lists 30 minutes of free calls. | ultravox.ai |
| Enterprise | quote-only | — | Custom / quote | Quote-only, so no monthly price is recorded: priority SLA, organizational support and fully customizable configuration. Rates negotiated. | ultravox.ai |
Last verified 2026-11-01. Re-verified against ultravox.ai/pricing on 2026-09-10. All three tiers, the $0.05/min rate, the $100 Pro platform fee and both SIP rates confirmed unchanged. ONE CORRECTION: an earlier version of this record recorded token pricing ($2.00 per 1M uncached input, $15.00 per 1M output) on the Pro plan only; the live page applies the same token rates to Pay as You Go as well, so they are now recorded on both. Compliance stays unrecorded across the board because the pricing page makes no HIPAA, SOC 2 or GDPR claim.

Pro. Re-read 2026-11-01: the price stands at $100. The note said the page publishes no bundled allowance at this tier; the page now reads "First 30 minutes free, $0.05/min after that."
Capabilities
Integrations: SIP trunking, Twilio, Model Context Protocol (MCP).
Key features: Speech-native model that consumes audio directly rather than chaining STT to an LLM, which removes a transcription hop from latency; $0.05/min for the model layer, positioned well below realtime-API alternatives; No surge pricing guaranteed on every tier, unlike vendors that double rates past concurrency limits; Built-in RAG corpora (20 on Pro) and an outbound call scheduler; Unlimited concurrency for a flat $100 rather than a per-tier ladder.
Plan limits: The $100 Pro fee includes zero minutes — it buys concurrency and features only, so all usage is additive; Pay-as-you-go is hard-capped at 5 concurrent calls, which rules it out for any production inbound line; No HIPAA, SOC 2 or GDPR statement appears on the pricing page, so regulated buyers must ask and nothing is asserted here; The 30 free minutes are a one-time allowance, not a monthly one; Token usage for text and threads is metered separately on every tier, on top of the per-minute voice rate.

This standing as a plaque
Ultravox currently holds a bronze deskmark here — Rank 13 of 13 · AI Voice Agents. Anyone may show it. There is nothing to apply for, nothing to pay, and displaying it changes no score: the standing comes from the published algorithm, which never reads commission data. We never ask anyone to show it, and its link carries rel="nofollow".
The image is drawn from our live data, so it follows the standing rather than freezing it: if Ultravox moves up or down a tier, the plaque on your own site says so at our next publish. Nothing is tracked beyond the ordinary web-server log that records any image request.
