What our research says

AutoCalls

AutoCalls is priced for small businesses and agencies rather than enterprise call centres: $27 gets you a working agent and two hours of calls, and the overage rate drops sharply as you move up the ladder. The GDPR documentation is genuinely thorough, naming the Romanian operating entity and setting out where it acts as controller versus processor. The catch is that minutes, not features, are what you are buying.

Pros

  • Starter tier is $27/month with 120 minutes included — a real entry point
  • Overage falls from $0.20 to $0.09 per minute at the higher tiers
  • 300+ named integrations covering CRM and scheduling
  • Explicit white-label tier at $355/month for agencies
  • Named EU operating entity with detailed GDPR controller/processor documentation

Cons

  • Minute bundles run out fast; the headline monthly price is not the real cost
  • No public developer API — the builder is no-code only
  • Language and integration counts are vendor claims we could not audit

Retell AI

One of the more honest voice-agent stacks: the pricing page breaks out infrastructure, TTS and LLM cost per minute so you can predict a call's cost instead of guessing. Telephony choice is wide and the concurrency allowance is generous. The catch is that per-minute billing plus add-ons makes a busy contact centre expensive fast, and the cheap end of the range only holds if you pick the cheap models.

Pros

  • Per-minute cost broken down by voice infrastructure, TTS provider and LLM on the public pricing page
  • Telephony via SIP trunking, Twilio and Vonage plus n8n, HubSpot, Make and Go High Level integrations
  • 20 concurrent calls included before any concurrency charge
  • Voice, chat and SMS agents share one platform and API
  • HIPAA path exists via a signed BAA covered in the terms of service

Cons

  • Cost per minute more than quadruples between the cheapest and most capable model combinations
  • Knowledge base, denoising, PII removal and branded caller ID are all metered extras
  • No flat-rate plan, so a spike in call volume lands straight on the invoice
