Dial - Phone Numbers for AI Agents vs. TrustSignal

Dial gives AI agents their own communication identity. Through a single REST API or MCP tool, agents can provision real US, Canadian, and international phone numbers and immediately send and receive SMS, WhatsApp messages, and voice calls - no carrier setup, no separate integrations for each channel. Dial is built for the agentic era, where AI agents increasingly need to act on behalf of users: signing up for services, completing 2FA/OTP verification, placing outbound calls with a local caller ID, and handling inbound communication across every channel.
