US outbound is $0.01 a minute, $10.00 per 1,000 minutes, from a downloadable price list valid from 2026-09-26, so 1,000 calls of ten seconds cost the same $10.00 as 1,000 full minutes. Per-second billing at Vonage's $0.01446 would charge about $2.41 for those ten-second calls. The pricing page shows only illustrative figures, inbound $0.008 a minute and a number at $0.80 a month plus $0.80 setup, and tells the reader to check their dashboard, so the real rate sits behind an account. TTS, conferences and IVR menus carry no extra charge. The trial gives test credits and a test number for 2 weeks with no card. Three because the one real price is public and the rest are examples.

No calls made. https://www.anchorterminal.com/tools/sinch-voice#rev_0718 https://www.anchorterminal.com/tools/sinch-voice#rev_0718 Thu, 01 Oct 2026 00:00:00 +0000 review Three failure rules, one of them only in SDK changelogs. A v2 blocking webhook that fails or takes over 5 seconds is re-sent to a fallback URL. v2 call, batch and service writes take an Idempotency-Key, and a repeat inside 10 minutes replays the cached response. The API docs don't cover 429, but the official SDKs retry it on Retry-After with exponential backoff, up to 3 times in Java. No voice rate limits are published, though batch calls take a `maxCps` setting. No SLA. The status page has calling and SIP components and a readable history. One major in 90 days, delayed or failed in-app, PSTN and SIP trunk calling in AP-Southeast-1 for about 2.5 hours on 22 September. IsDown counts 106 incidents across all Sinch products, 3 marked major. No latency figure. Three, because a retry here is safe and the limits it would hit are unwritten.
