What our research says

Dialora.ai

Feature-for-feature this looks like the rest of the mid-market voice agent field: booking, transfer, knowledge base, transcripts, five languages, an API. What sets it apart, and not in a good way, is how little of the commercial side is nailed down, from a pricing page that shows no prices to a terms page with an unfilled template placeholder.

Pros

  • Handles both inbound answering and batch outbound dialling
  • Books directly into Cal.com and Google Calendar
  • Live transfer to a human plus post-call transcripts and sentiment analysis
  • Documented API and an n8n integration for workflow automation
  • Five spoken languages listed, including Turkish and Portuguese

Cons

  • Pricing page displays no prices, and the site's own metadata gives two different starting figures
  • No call-minute allowances or overage rates published
  • No legal entity, registered address or country disclosed
  • Comparison pages against competitors are marketing content, not verified benchmarks

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
