Editorial Verdict

AI-researched, not hands-on tested

Sub-500ms average latency and 99.9% enterprise uptime, with SOC 2/HIPAA/PCI compliance, make Vapi's technical foundation genuinely solid on paper. Real per-minute costs run well above the advertised $0.05/min starting rate, latency occasionally spikes to several seconds despite the marketing, and it owns no telephony network -- uptime depends on carriers like Twilio underneath it.
