The concurrent dial limit per workspace is raised on request with no number, the OpenAPI file documents no 429, and there's no SLA. status.vogent.ai shows 90-day uptime bars at 100 per cent for the API and posts no incidents, with no incident log behind the bars. An empty list with no log behind it proves little, and I don't trust it yet. There's no public changelog and no release the dossier could find since the web client on 23 January 2026. No latency figure published. Two, because the retry safety is real and everything around it is silent."
