What our research says

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

Vozexo

Vozexo's dental-specific framing — after-hours toothache calls that need same-day booking — is a sharper pitch than a generic AI receptionist, but the underlying product is a general phone-answering agent that also serves other service businesses. The per-minute overage charges on every tier mean a busy month can cost noticeably more than the sticker price.

Pros

  • CRM and calendar integrations (HubSpot, Salesforce, Google, Outlook) out of the box
  • Warm transfer to a human agent when the AI can't resolve a call
  • Dental-specific positioning around after-hours emergency booking

Cons

  • Per-minute overage fees apply on every tier once included minutes run out
  • No free trial tier described — paid plans start immediately at $29/month
  • Parent company and location are not disclosed on the site
