Build Vapi
KINDAback to the verdict
Before step 1
you will need
- public Linux VM, domain, TLS, and correctly restricted SIP, WebRTC, and RTP ports
- SIP trunk and phone number from a carrier such as Telnyx
- STT, LLM, and TTS provider API keys
- country-specific consent, recording, caller-ID, and outbound-calling review before real traffic
Delivery order
Scaffold the smallest runnable application and document its commands.
done whenThe project starts from a documented command in a clean checkout.
Implement the primary data model and core workflow.
done whenThe main object can be created, read and changed end to end.
Add validation, safe failure states, and persistence.
done whenBad input is refused with a readable message and nothing is left corrupted.
Cover the critical path with automated tests.
done whenThe highest-risk behavior fails the suite when it breaks.
Exercise a clean install from the README and fix every missing step.
done whenA fresh clone reaches the first successful workflow using only the README.
That is the whole plan for Vapi. What it deliberately does not cover is below · check the gaps before you call it a replacement.
- managed realtime infrastructure, scaling, provider failover, and support
- assistant, squad, workflow, phone-number, and provider configuration APIs
- outbound campaigns, carrier integrations, spam mitigation, and production telephony debugging
- hosted simulations, evaluations, call logs, recordings, analytics, and retention controls
- enterprise SLAs, compliance add-ons, role controls, and data-residency options
