AvaritCall vs Retell AI
Two ways to run AI phone agents: one assembled rate you predict up front, or four components you select and add up.
AvaritCall and Retell AI both run AI voice agents on real phone calls, but they package cost differently. Retell publishes $0.07–$0.31 per minute, built from a $0.055 platform rate plus separately billed speech-to-text, text-to-speech, language model and telephony. AvaritCall charges a single $0.08 per minute with those components included, and operates its own telephony layer rather than reselling a third party's.
The honest difference here is not which platform is better, but which cost model and which level of assembly fits the team buying it. Retell is built for people who want to choose every component; AvaritCall is built for people who want the phone operation to work without choosing any of them.
What each is best for
Best for teams that want a running phone operation, not a stack to assemble
One rate covers speech recognition, the language model, speech synthesis and telephony. The admin panel, iOS app and built-in CRM mean the operation can be run by the team that owns the calls, not only by the team that writes code.
Best for developers who want to select every component themselves
Retell exposes the stack: you choose the TTS provider, the language model and the telephony carrier, and pay each at its own rate. If your team already has strong opinions about those choices — or existing Twilio/Telnyx contracts — that flexibility is genuinely valuable.
Side by side
| Criterion | AvaritCall | Retell AI |
|---|---|---|
| Headline rate | $0.08 / min | $0.07 – $0.31 / min |
| What the rate covers | STT, LLM, TTS and telephony — one line on the invoice | Platform $0.055/min; TTS $0.015–0.040, LLM $0.003–0.16 and telephony $0.015 (US, Twilio) added on top |
| Telephony | Own telephony layer — codecs (Opus), echo cancellation, connection and channel management | Twilio, Telnyx, or your own SIP trunk (no charge for custom SIP) |
| Concurrency | Plan-based; very high concurrency on the enterprise plan | First 20 concurrent calls free, then $8 per concurrency / month |
| Credit to start | $5 signup credit, $10 minimum top-up | $10 in free credits |
| Optional add-ons | Email report $0.001, WhatsApp report $0.005, IVR voice generation $0.15 / 1,000 characters | Knowledge base $0.005/min (+$8/mo per base after 10), advanced denoising $0.005/min, safety guardrails $0.005/min, PII removal $0.01/min, branded calls $0.10/call, phone numbers $2/mo |
| Product surface | Admin panel, iOS app with push notifications, built-in CRM, REST API and webhooks | Developer dashboard and API |
| Turkish | Optimized for Turkish phone conversation; Turkish voices trained in-house | Depends on the STT/TTS providers you select |
| Call recordings | Audio is not recorded; only text transcripts are stored | Recording and QA tooling available (AI quality assurance $0.10/min after the first 100 minutes) |
Strengths and weaknesses
- One predictable rate — the invoice does not change because a model or voice provider changed its price
- Telephony is built and tuned in-house rather than rented, so the whole audio path can be optimized
- Turkish is a first-class target, not a locale setting: dedicated turn-taking and in-house trained voices
- Panel, iOS app and CRM ship with the product — no front end to build around an API
- Audio is never recorded, which removes a whole category of consent and storage problems
- You cannot swap the STT, LLM or TTS provider component by component
- Smaller developer ecosystem and community than the US-based platforms
- No audio recordings — if your QA process depends on listening back to calls, that is a real gap
- Brand recognition in the US and Western Europe is still limited
- Component-level choice: pick your own TTS, language model and carrier
- Rich operational add-ons — PII removal, safety guardrails, denoising, AI quality assurance
- First 20 concurrent calls carry no concurrency fee
- Works with existing Twilio or Telnyx contracts, or a custom SIP trunk at no extra charge
- Mature developer ecosystem and documentation
- The real per-minute cost is an addition problem: platform + TTS + LLM + telephony, each variable
- The published ceiling is $0.31/min — roughly four times the AvaritCall rate
- Several operational features that arrive included elsewhere are metered add-ons
- Telephony quality and latency depend on a third-party carrier, outside Retell's own stack
Who should choose which
- You want to know the per-minute cost before the month ends, not after
- Turkish calls are a meaningful part of the volume
- You want a panel, mobile app and CRM rather than an API and a to-do list
- You would rather one company be accountable for the whole audio path
- You want to select the language model and voice provider yourself and change them at will
- You already have Twilio or Telnyx contracts you intend to keep
- Your team is building its own interface on top of a voice API
- You need the metered compliance add-ons — PII removal, guardrails — as discrete controls
