■ Telnyx
Carrier-grade voice, SMS, and eSIM APIs — agent-accessible communications infrastructure.
Telnyx provides programmatic access to carrier infrastructure: voice calls, SMS, SIP trunking, and eSIM. Agents can make and receive calls, send SMS, and provision mobile connectivity. Not exclusively agent-focused but fully API-accessible with no human steps required.
