AgentPhone
AgentPhone gives AI agents their own US or Canadian phone number for voice and SMS through one API call and one unified webhook.
If you're building an agent that needs a North American number, AgentPhone cuts most of the telecom work: one call to buy the line, one webhook for voice and text, MCP tools so the agent can provision its own number. The rate card models cleanly — $3 per number plus 13¢ a minute self-run, 22¢ hosted. Skip it if you need numbers outside the US and Canada or anything resembling IVR; Twilio and Telnyx still own that ground.

Skip AgentPhone if you need phone numbers outside the US and Canada, or you want a no-code virtual phone system with IVR and call routing rather than a webhook and an API key.
Inbound SMS costs the same as outbound — 2¢ per segment in both directions, so a 2FA-heavy agent pays on every verification code it receives, not just the ones it sends.
Usage-based with no minimum and no contract, AgentPhone fits a solo developer or small agent team spending tens to low hundreds a month, and scales linearly into the low thousands for high-volume SMS and voice workloads. It is cheaper than standing up a CPaaS stack plus the transcription and threading glue you would otherwise build, but for pure high-volume telephony at commodity rates Twilio and Telnyx still undercut it. iMessage at $150–$250 per line per month is a premium channel, not a

What is AgentPhone?

Best for Developers shipping AI agents that need a US or Canadian phone number with voice and SMS, Sales and outreach teams automating lead follow-up by call and text from an agent, Agent builders who want number provisioning and messaging as native MCP tool calls.

AgentPhone is a telephony API where the caller is an AI agent, not a person holding a handset. A single POST creates the agent persona; a second call provisions a US or Canadian local number with voice and messaging already switched on. Inbound calls get transcribed live and land on your webhook as text; your agent answers with text and AgentPhone handles text-to-speech on the way back out. Calls and messages share one event shape, so you maintain a single handler rather than two pipelines. Authentication is a Bearer API key against https://api.agentphone.ai/v1, with HMAC-signed webhook events (agent.message, agent.call_ended) so your endpoint can verify what it receives. Beyond plain SMS you get MMS, group threads, reactions, and iMessage lines with read receipts and typing indicators; WhatsApp Business and RCS are available in beta when switched on for your account. Provisioning, sending, and call handling also run as MCP tools, letting Claude Code, Cursor, OpenClaw, Windsurf, or any MCP client buy a number through native tool use. Python and Node.js SDKs cover the non-MCP path. You decide who runs the voice agent. Route calls over your own webhook at 13¢ a minute, or let AgentPhone host an LLM behind the number at 22¢ and skip the orchestration. Sub-accounts give resellers their own numbers and usage on one rolled-up bill, and SIP trunking points numbers at your existing voice stack. In May 2026 AgentPhone shipped an official Vercel Chat SDK adapter that pipes SMS, MMS, iMessage, and voice transcripts into Slack, Teams, and Discord. Pricing is pure usage: $3 per number per month, 13¢ per voice minute billed per second, 2¢ per SMS segment, 3¢ per MMS, and $5 of starting credit with no monthly minimum or contract. Against Twilio or Telnyx, AgentPhone trades routing depth for agent-shaped defaults — unified webhooks, conversation threading, MCP, and hosted voice in the box.

Behind the verdict
Reach for AgentPhone when the phone number is a feature of your agent, not a product you're building. That covers lead follow-up that dials a prospect the moment a form is submitted, an on-call bot that pages a human when a check fails, or a receptionist persona that answers and texts back without a person in the loop. The economics stay attractive at small volume — a number and a few hundred minutes a month costs less than lunch, and there's no seat or platform fee inflating a demo into a procurement conversation. What sold us on the architecture is the single event shape. Anyone who has wired Twilio voice and SMS separately knows the tax: two status models, two error surfaces, two sets of retries. AgentPhone collapses that into one handler, then signs the payloads with HMAC so you aren't accepting anonymous JSON. Automatic conversation threading means a call and a follow-up text belong to the same thread without you building a correlation table. Who runs the voice model is the sharpest fork in the product. Handing AgentPhone the LLM at 22¢ a minute gets you live in an afternoon, but your prompt, tone, and tool access live inside someone else's runtime. Bringing your own agent over webhook at 13¢ keeps control and costs less per minute, provided you can absorb real-time transcription and TTS latency in your own stack. Most teams serious about voice quality end up on the webhook path eventually. The math is unforgiving once volume climbs. Our modeled month — three numbers, 1,500 voice minutes, 10,000 SMS segments — lands near $404, and messaging dominates it. If your workflow is text-heavy, budget accordingly; 2¢ a segment adds up faster than people expect. Call recording is a flat $5 a month across every number on the account, which is a refreshingly small line
Limitations
- AgentPhone provisions US and Canadian numbers only, and everything runs through a developer surface: a unified webhook, Python and Node.js SDKs, a REST API, and an MCP server.
- There is no IVR builder, no call-routing tree, and no contact-center dashboard.
- Pricing is purely usage-based with no plans or seats — numbers at $3 per number per month, voice at 13¢ a minute when your agent runs over webhook and 22¢ a minute when AgentPhone hosts it, SMS at 2¢ per segment inbound or outbound, MMS at 3¢ per message, and iMessage lines from $150 a month.
- Inbound costs the same as outbound for SMS and MMS.
- Voice is billed per second and rounded to the nearest cent per call; recording is a $5/month account add-on.
- US numbers that send text must be carrier-registered from the dashboard, and SIP trunking requires requesting access.
- A segment is 160 characters, or 70 when the message includes emoji or non-Latin script.

GeneratedReal-world workflow fit
Concrete scenarios for the personas AgentPhone actually fits — and what changes day-one when you adopt it.
You create an agent with POST /v1/agents, provision a number with POST /v1/numbers, attach it, and point a webhook at your server to receive agent.message events.
Outcome: Your agent is answering inbound texts and calls the same afternoon, with the $5 starting credit covering the number and roughly 100 texts before you add a card.
You add the agentphone entry to your mcpServers config (command npx, args agentphone-mcp) so the coding agent can call phone tools natively.
Outcome: The agent texts you a build status or places a call through tool use without you writing any telephony glue code.
You create a sub-account per customer so each one gets their own numbers and usage, running either the hosted agent at 22¢ a minute or their own webhook at 13¢.
Outcome: One rolled-up bill covers every customer, and custom per-customer rates are available on request.
Use cases
- AI sales agent places lead follow-up calls and logs the transcript back to your CRM
- Autonomous agent receives 2FA and verification codes over SMS and voice
- AI scheduler takes inbound booking calls and confirms appointments by text
- Support bot answers calls, streams live transcripts, and posts summaries
- AI sends parcel and appointment updates to customers over SMS and MMS
- Coding agent in Claude Code or Cursor texts you status updates from a tool call
- On-call engineer gets paged by an AI agent that places an actual phone call
- A platform resells agent telephony to its own customers through sub-accounts
Setup time & first value
How long it actually takes to get something useful out of AgentPhone — broken out by persona, not the marketing-page minute.
A developer with an API key can create an agent, buy a number, attach it, and set a webhook in about 15–30 minutes following the five-step quickstart. Wiring the MCP server into Claude Code or Cursor is a one-line mcpServers config change. Going live on SMS adds carrier registration review time for US numbers, which you file from the dashboard.
Switching to or from AgentPhone
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Twilio: repoint your number provisioning and messaging to POST /v1/numbers and the unified webhook, or keep your voice stack and attach it via SIP trunking at $0.00374/min inbound.
- →From a hand-rolled Twilio plus transcribe pipeline: drop the transcription glue and consume agent.call_ended for the post-call summary and full transcript.
- →From a shared team SMS gateway: move each customer onto a sub-account so their numbers and usage land on one rolled-up bill.
- ↗To Twilio: export your number list and re-provision on Twilio Programmable Voice and Messaging if you need numbers outside the US and Canada.
- ↗To Telnyx: port US and Canadian numbers across and rebuild the conversation threading and transcription layers yourself.
- ↗To a no-code virtual phone system: if IVR and agent dashboards become the requirement, AgentPhone has no equivalent surface to migrate to.
