OpenPhonex · the phone layer for AI agents
Developer API and MCP for teams that move fast. Implementation services for production deployments that need to work. Connect your AI agent, review the evidence trail, request numbers, and go live with the right controls in place.
Every call: recording · waveform · transcript · summary · policy decision · cost
The call above is a simulation. Dial our live English-speaking AI demo and talk to it yourself — ask anything, or book a demo.
“Hi! This is the OpenPhonex demo assistant. Ask me anything, or say you want to book a demo.”
Two ways to start
Most phone infrastructure was designed for humans dialing in — not agents routing in and out. Connect the agent you already run, no number required to start. Or have OpenPhonex design, build, and operate the workflow with you.
Connect your existing agent by webhook, realtime audio, API, or MCP. OpenPhonex handles the number path, calls, SMS, recordings, transcripts, compliance checks, and usage evidence around it.
Need the phone workflow in production, not just the infrastructure? We scope the call flow, configure guardrails, integrate your systems, handle number onboarding, and hand over a running agent with observability from day one.
Where it fits
The same phone layer works for customer-facing agents, internal operations, and agent teams building for clients.
The evidence
Debugging a voice agent takes more than a call log. Every call produces a waveform, recording, transcript, AI summary, status timeline, policy decision, and cost breakdown — in the dashboard and via API.
Compliance is infrastructure, not onboarding paperwork. Every call runs through policy evaluation before completion — enforced at the platform level, active from the first session, logged next to the recording and transcript.
Healthcare solicitation, political calls, emergency use, debt collection, robocalling, telemarketing, mass outreach, scraped-list campaigns, caller-ID spoofing, and cold outbound sales — refused by default.
Support, appointments, reservations, status updates, personal errands, and operational calls — approved on a predictable path. A2P registration and SMS consent ride along with SMS route activation.
Recording disclosure stored as its own event per session, country-required announcements enforced before recording begins. Query what the compliance layer evaluated — per call, via dashboard or API.
Go live
Request dedicated numbers, SMS routes, outbound access, and country registrations only after the flow is proven. OpenPhonex handles provider selection and the registration paperwork — requirements, typical activation time, and restrictions in plain language, before you commit.

Two ways to run it. Either way, OpenPhonex manages numbers, billing, compliance, and policy — self-hosting means your call audio stays on your infrastructure.
Fastest path. OpenPhonex manages provider accounts, provisioning, billing, compliance, hosted gateway, recordings, and platform ops. You connect your agent and build.
Pay for numbers, minutes, SMS, hosted gateway, recordings, and platform ops.
Your gateway processes call audio on your infrastructure while OpenPhonex manages numbers, billing, compliance, and policy. For latency-sensitive or data-residency workflows.
You operate gateway uptime, network access, local storage, and media upgrades.
Agent-native
A coding agent can read these docs and wire the whole thing — check coverage, request a number, inspect recordings, send approved SMS. Delegate the setup instead of hand-wiring every telecom step.
Read /llms.txt and /openapi.json. Connect my agent to OpenPhonex, check coverage, request the right number, and inspect every recording, transcript, policy decision, and cost event.Agents, calls, recordings, SMS, usage, numbers, coverage.
Provision, call, and query — no human steps in the loop.
Every call event, plus a bidirectional audio stream.
Node.js and Python, with an interactive API reference.
Agent-install quickstart for the whole setup flow.
Machine-readable entry point for AI assistants.
Your feedback
Rate the call and leave a quick note — all optional.
Start
Bring your own AI agent, choose the phone numbers it needs, and keep every call or message observable from day one. Talk to an engineer if you want OpenPhonex to design and operate the workflow with you.
