Agentphone

AgentPhone

AgentPhone is an API-first telephony platform for AI agents. Give your agents phone numbers, voice calls, and SMS — all managed through a simple API.

When to Use

• Use when the user wants to create or manage AI phone agents, voice agents, or telephony automations
• Use when the user needs to buy, assign, release, or inspect phone numbers tied to an agent workflow
• Use when the user wants to place outbound calls, inspect transcripts, or send and receive SMS through AgentPhone
• Use when the user is configuring webhooks, hosted voice mode, or account-level usage for AgentPhone
• Use only with explicit user intent before actions that spend money, send messages, place calls, or release phone numbers

Core Workflow

1. Confirm the request matches this skill's trigger, scope, and risk profile.
2. Use the topic map to identify the relevant pattern, checklist, or example before writing detailed guidance or code.
3. Load references/full-guidance.md when implementation details, examples, anti-patterns, validation checks, or edge cases are needed.
4. Apply only the relevant guidance instead of loading or repeating the entire reference by default.
5. Verify the result against any validation checks, limitations, security notes, or platform constraints in the reference.
