Vapi
Vapi is a voice-call platform available on the web and iOS. It supports inbound and outbound calls, human handoff, concurrent calls, and custom phone numbers. The usage-based No Success Package is listed at free and includes $5 in starter credits, one Vapi phone number, four concurrent calls, and full platform access. Core costs $29 a month, billed monthly, and includes five phone numbers, 10 concurrent calls, 30 days of raw data retention, and email support. Pro costs $999 a month, billed monthly, and includes 10 phone numbers, 30 concurrent calls, 180 days of raw data retention, RBAC, ZDR, and a 99% uptime SLA. Premier uses custom pricing; its listed options include custom phone-number counts and custom RBAC, ZDR, and SSO, with dedicated SIP available. The service listing says there is no free plan, although the No Success Package is presented at no cost with starter credits. Plan allowances vary, so the listed overall concurrent-call figure of 10 is not the allowance for every package.
