Customer support decision
8call
A single competent developer can build a useful, smaller 8call replacement by wiring telephony + STT/TTS + an LLM and a simple DB-backed UI; existing open-source projects (microsoft/call-center-ai) cover the core technical flows.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All 8call alternatives, with the arithmetic →
What a replacement has to do
- Receive inbound call → transcribe speech → run intent/response model → synthesize reply and place outbound audio → log call and metadata
What it still won’t have
- Hosted SLA, monitoring and uptime guarantees
- Proprietary integrations and prebuilt connectors to CRMs or business tools
- Polished UX, onboarding, and support
- Potential economy of scale on telephony and model usage discounts
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
8call does not publish a price we could read, so there is nothing to compare against. What building costs is below.

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted AI call-agent using Node.js (or Python) + Postgres + simple React admin UI. Core features in scope: receive and route PSTN calls via Twilio, record and stream audio to a speech-to-text API, call an LLM API for intent and response generation, synthesize reply audio (TTS) and play back to caller, store call recordings and transcripts in Postgres, and expose a web UI for searching call logs and listening to recordings. Out of scope: multi-tenant billing, advanced CRM integrations, and analytics dashboards. Include retry/error handling for telephony and ML API calls, basic authentication for the UI, containerized deployment (Docker), and unit/integration tests for the telephony, STT, LLM, and TTS flows.
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 2 cited sources+1
- Evidence score58
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
