AgentLine connects AI agents to the public phone network without requiring separate telephony providers or SIP configuration. You assign a real phone number to an agent, which can then place outbound calls, send SMS messages, and automatically handle inbound conversations. The entire setup is packaged as one skill, making it straightforward to add voice and messaging capabilities to existing agent workflows. Practical use cases include AI-driven customer support lines, appointment reminder bots, outbound lead qualification, and two-way SMS automations — anywhere a phone interaction replaces or supplements a chat or web touchpoint.
