AgentCall

AgentCall provides a REST API that lets AI agents obtain real SIM phone numbers, send and receive SMS, and make or receive voice calls. Users can provision numbers by country and capability, then link an agent with a single API key, eliminating the need for a human dashboard. All inbound communication—including messages, verification codes, and call transcripts—is delivered asynchronously to a webhook endpoint.

The service includes programmable AI‑generated voice calls: an agent can initiate a call using a chosen voice style, conduct a conversation driven by a system prompt, and receive a full transcript. Inbound calls can also be answered autonomously by an AI voice configured per number, without additional webhook handling.

Features such as non‑VoIP numbers that pass platform verification, isolated numbers per agent, and searchable SMS inboxes aim to simplify phone‑based interactions for agents in sales, support, finance, healthcare, and other domains. A free tier is offered, with usage billed per minute for voice calls.
