Decision notes
Official-document research
Based on the cited documentation. We did not use the product, purchase a plan, or run quality, speed or reliability tests in this review.

- Operators able to monitor permissions and spend
Choose another approach if
- Assuming trial credits or concurrency are free minutes
- Standalone voice resale or unapproved intermediary services
Pricing and conditions
Documented terms
The page shows $10 trial credits and a headline $0.07–$0.31/minute, not a universal ceiling. Example components are $0.055/min voice infrastructure plus $0.015/min platform voice, then the selected LLM, telephony and add-ons. Connected silence/hold counts; time is accumulated to seconds. AI charges stop at transfer, telephony can continue. Twenty concurrent calls means capacity, not free minutes; extra capacity is $8/concurrency/month, with numbers and other recurring items separate. The read pages did not confirm ISO currency, tax inclusion or destination-specific total. Terms describe monthly billing/renewal; remove subscription items or close the workspace to stop those renewals.

Pricing or terms sourceCode, model and service licensing
Hosted access and generated content are licensed for personal/internal business purposes, not code/weight ownership or exclusive output. Terms restrict standalone resale of voices, competitive training and intermediary substitutes; agency/reseller documentation does not override the signed contract. Input remains yours subject to service-use permissions. Unless recording is opted out, terms allow de-identified/aggregated communications for service-model training and improvement. Retention depends on purposes, customer instructions and legal needs, with US/other-country processing; recording opt-out is not proof of no metadata. Obtain caller/recording consents, required AI disclosures and a signed BAA before HIPAA data; third-party voices/models and output copyright need separate clearance.
Basis and limits of the recorded score
The existing 4.5 score is retained; its original scoring evidence is unavailable. This documentation review did not measure performance or compare products and did not re-score it.
Overview
Retell combines telephony or web calls, speech recognition, selected models and speech synthesis in a configurable agent workflow. The documentation describes knowledge-based answers, appointment tools, human transfers, APIs and monitoring. Interruptions and turn-taking are supported features, not a measured latency or human-indistinguishability result from this directory.
Budget for the whole call path. Silence and hold time can still count as connected call time; after a human transfer the AI fee stops but telephony can continue. Model, voice, phone route, storage settings and optional features all affect cost and data handling. Decide call/recording consent, disclosure, escalation and retention before connecting live callers.
