AvaritCall vs Retell AI: Pricing, Features and Capacity Compared (2026)

AvaritCall and Retell AI both run voice AI agents on real phone calls, and either can be the basis of an AI call center. The real difference is how cost is packaged. Retell publishes $0.07–$0.31 per minute for voice agents, built from a $0.055 infrastructure rate plus a separately priced language model, voice, telephony and optional add-ons [1]. AvaritCall charges $0.08 per spoken minute for its AI phone assistant, billed per second, with no number or line rental fee.

What this comparison comes down to is what each cost model puts on the team buying it. On Retell you choose the language model, the voice and the telephony provider yourself and pay for each separately. On AvaritCall you do not pick separate line items for speech recognition, the language model or speech synthesis; besides the per-minute pricing, only agent instructions ($0.005 per call for every 10,000 characters) and the messaging or voice-generation items you use are billed. Ringing time and unanswered calls are free; signup includes a $5 credit and no card is required.

Which AI phone assistant fits which team?

AvaritCall: for teams that want a running phone operation without assembling components

The spoken minute is a single rate; speech recognition, the language model and voice are not billed separately. Your existing line connects through NetGSM, Verimor, Netsantral or your SIP PBX, with no number or line rental fee. The admin panel (transcripts, summaries, tags), AvaritCall CRM, AvaritCall calendar (Cal.com, beta) and AvaritCall integrations mean the operation can be run by the team that owns the calls, not only by the team that writes code; a REST API, webhooks and MCP are available as well.

Retell AI: for developer teams that want to select every component themselves

Retell exposes the stack: you choose the voice provider, the language model and the telephony carrier, and pay each at its own rate. It publishes SOC 2 certification, a HIPAA-ready setup and a BAA on its enterprise plan; calls are tracked to the second with no per-call rounding, and the agent fee stops after a transfer [1]. If your team has strong opinions about those choices, or existing Twilio/Telnyx infrastructure, that flexibility is genuinely valuable.

Side by side: pricing, features and capacity

Strengths and weaknesses

AvaritCall: strengths

• One per-minute line item: per-second billing, ringing time and unanswered calls free
• No number or line rental fee; connect an existing NetGSM, Verimor or Netsantral line or a SIP PBX
• Panel, AvaritCall CRM, AvaritCall calendar (Cal.com, beta) and transfer to a human with a summary ship with the product
• Audio is never recorded; transcripts are stored with automatic masking, which reduces the retention burden under KVKK/GDPR
• Average response time of about 0.8 seconds (internal measurement)

AvaritCall: limitations

• You cannot swap the speech recognition, language model or voice provider component by component
• No audio recordings; if your QA process depends on listening back to calls, that is a real gap
• For US-focused projects that require SOC 2 or HIPAA documentation, Retell’s published compliance options stand out

Retell AI: strengths

• Component-level choice: many voice providers and language models, speech-to-speech models and a custom LLM option
• No base platform fee, $10 starting credit and the first 20 concurrent calls free
• Tracked to the second with no per-call rounding; failed calls are not billed and the agent fee stops after a transfer
• SOC 2 certification and a HIPAA-ready setup; BAA, SSO and role-based access on the enterprise plan
• Rich add-ons: PII removal, safety guardrails, denoising, AI quality assurance, batch calls, SMS
• Ready telephony through Twilio/Telnyx or your own SIP trunk at no charge; multilingual agents, Turkish included

Retell AI: limitations

• The real per-minute cost is an addition problem: infrastructure + language model + voice + telephony + add-ons, each depending on your choices
• The top of the published $0.07–$0.31/min range is roughly four times the AvaritCall minute rate; with the most expensive language models, cost can exceed that range
• Every concurrent call above 20 adds an $8 monthly subscription
• Türkiye is not on the ready telephony list; Turkish lines require connecting your own SIP trunk

Choose Retell AI if

• A SOC 2 report or HIPAA/BAA is a procurement requirement
