# AgentCall: Phone Numbers for AI Agents

## Current offer and agent behavior

New accounts receive a one-time 72-hour live trial with one US/Canada local number, 300 managed inbound AI seconds (five minutes) total, and five SMS send attempts to verified destinations. Card verification is required before number allocation; the clock starts when allocation succeeds. There is no monthly reset or automatic paid subscription. Live OTP extraction and outbound calls require Pro.

Existing Free accounts retain their assigned monthly allowances. Read the account's offerVersion, trial and limits rather than assuming every Free account has the same offer. Only describe a monthly reset when the account response supplies a non-null resetsAt.

Pro is $19.99/month plus number rental and usage: local/mobile numbers $2/month each, toll-free $2.50/month, outbound SMS $0.015/message, standard outbound voice $0.035/min, managed AI voice $0.40/min, BYOK voice $0.10/min plus your AI provider's charges, or Premium Voice $0.59/min. AI calls round up to whole minutes per call. New-account destination/business verification can still apply after upgrading.

After trial expiry, the number is held for at least 48 hours before release, with a successful expiry notice before release becomes eligible. A delayed notice extends the hold. Trial expiry and number retention are separate; stored configuration and results remain available. Upgrading during the hold preserves the number.

Before quoting allowances or taking a paid action, call get_plan (or GET /v1/account) and use the returned offerVersion, trial, limits, billingStatus and summary. New live_trial_72h_v1 accounts have a one-time 72-hour trial starting at successful number allocation, 300 managed inbound AI seconds total and five verified-destination SMS attempts; card verification is required first. No monthly reset, automatic upgrade or Free overage. Existing free_monthly_v1 accounts retain assigned monthly allowances. Live OTP extraction, outbound calls, BYOK and Premium Voice require Pro for new trial accounts. Explain payment_method_required, payment_recovery_required, trial expiry and quota errors; stop retrying them. Share the returned setup/upgrade link when the user wants to proceed, let the human complete card/payment steps, then reread get_plan before retrying. Do not assume saving a card upgrades the account, or promise a released number can be recovered. Pro is $19.99/month plus number rental and usage. Do not auto-run upgrade_to_pro just because another tool failed. Honor the user's authorization for any real-world action. Read https://api.agentcall.co/llms.txt for the current reference.

You have access to the AgentCall API for phone numbers, SMS, voice calls, and AI voice calls. Inbound and outbound calls can both be answered or initiated by an AI voice agent.

# AgentCall: Phone Numbers for AI Agents

skill-card.md

## Description:

AgentCall gives agents access to real phone numbers for SMS, authorized OTP retrieval, voice calls, AI receptionists, proactive messages, and call memory through the AgentCall API.

This skill is ready for commercial/non-commercial use.

## Publisher:

[kintupercy](https://clawhub.ai/user/kintupercy)

### License/Terms of Use:

MIT-0

## Use Case:

Developers and operators use AgentCall to let an agent provision phone numbers, send and receive SMS, answer or place calls with AI voice, retrieve authorized OTPs, schedule proactive messages, and maintain call memory. It is suited for authorized business communication and agent-to-phone workflows that require user confirmation for real-world actions.

### Deployment Geography for Use:

Global; telephony features depend on AgentCall's documented carrier and destination support.

## Known Risks and Mitigations:

Risk: The skill can make real-world calls, send SMS messages, and trigger billing.

Mitigation: Review costs and require explicit user confirmation before outbound calls, texts, number provisioning, premium voice, recording, schedules, or other paid actions.

Risk: OTP retrieval can be misused against services the user does not control.

Mitigation: Use OTP workflows only for systems the user owns or is authorized to test.

Risk: Call recording and call memory can retain sensitive communications.

Mitigation: Confirm recording consent, monitor retained call memory, and disable or purge configurations when no longer needed.

Risk: Persistent AI receptionists, schedules, and webhooks can continue acting after initial setup.

Mitigation: Monitor active configurations and disable receptionists, schedules, webhooks, or memory when the user's task is complete.

  "summary": "Phone numbers, SMS, two-way AI SMS plus relay mode (text your own agent on a real number), proactive scheduling (the agent texts first: appointment reminders and recurring digests), AI voice agents (Managed $0.40/min, BYOK $0.10/min, or Premium Voice $0.59/min on inbound + outbound) with 31 languages plus auto-detect, and Auditable Call Memory (cross-call contacts, structured call reports, the next-call context block) for AI agents. 62 tools. VoIP-routed via licensed US carriers.",
  "description": "Phone numbers, SMS, voice calls, inbound + outbound AI voice with multilingual support, AND Auditable Call Memory for AI agents. Provision US/CA numbers, send/receive texts, extract OTP codes for apps you control, configure phone numbers to be answered by an AI voice agent (with plain-English email summaries and optional MP3 recordings after every call), or place autonomous AI-powered outbound calls. Inbound texts can be answered too: set smsMode to 'ai' so AgentCall's AI replies and pulls real quotes by calling tools you host through the action bridge, or set smsMode to 'relay' so AgentCall runs no AI and forwards each text to your own agent and sends its reply back, letting you text your own agent on a real number. AI voice supports 31 languages plus auto-detect on both directions: English, Spanish, French, German, Italian, Portuguese, Dutch, Japanese, Korean, Chinese (Mandarin), Hindi, Arabic, Russian, Indonesian, Turkish, Polish, Ukrainian, Vietnamese, Tamil, Malay, Romanian, Greek, Czech, Swedish, Hungarian, Danish, Finnish, Norwegian, Slovak, Croatian, and Bulgarian. Default is auto (matches the caller naturally); pin a specific language to keep the AI in that language even if the other party speaks another, useful for businesses serving a specific language community or for outbound errands like booking a Spanish doctor's appointment on behalf of someone. Inbound AI voice ships in two billing modes per number: Managed at $0.40/min (AgentCall holds the AI provider key, simplest setup) or BYOK at $0.10/min (customer provides their own AI provider key, AgentCall bills only the platform overhead). Premium Voice is an opt-in Pro add-on that answers inbound calls with a more natural, brandable voice from a curated library, in the same 31 languages as the standard voice plus auto-detect, with full caller memory, at $0.59/min only on numbers where it is enabled. Enable it per number from the dashboard or programmatically via the set_premium_voice MCP tool (disable_premium_voice to revert, list_premium_voices to browse). Memory is included on every plan and every voice mode. Every completed AI call auto-extracts into structured, source-backed memory: contacts, facts, preferences, commitments, tasks, briefs. Cross-call memory means a returning caller is recognized and the AI starts with what was said last time. Ask AgentCall what is known about any phone number before placing a call via get_nex
