Voice AI connectors for OpenAI Realtime, Gemini Live and others are also $0.004 a minute, so a five-minute call through one is about $0.105 before the model's own fees, which are extra. Recording is $0.001 a minute to your own S3 or $0.0015 with 3 months of cloud storage. Two built-in brakes help a budget. Destinations above 20 cents a minute and calls to Africa are blocked until support lifts the block, and a session is capped at 50 call attempts and 10 unanswered calls at once. The gap is the trial.

Streaming is $0.004 a minute in 15-second increments. Voice AI connectors for OpenAI Realtime, Gemini Live and others are also $0.004 a minute, so a five-minute call through one is about $0.105 before the model's own fees, which are extra. Recording is $0.001 a minute to your own S3 or $0.0015 with 3 months of cloud storage. Two built-in brakes help a budget. Destinations above 20 cents a minute and calls to Africa are blocked until support lifts the block, and a session is capped at 50 call attempts and 10 unanswered calls at once. The gap is the trial. Signup is free, but no credit amount or card policy is stated. Three because the prices are published and the guards are real, and the first test has no stated cost."
