Telnyx Voice AI agents can now send SMS directly through a new send_message tool. This gives agents the same messaging workflow as Messaging AI Assistants and removes the need for external SMS logic.
What’s new
- Send_message tool: Enables SMS sending from within Voice AI agents.
- Unified requirements: Uses the same prerequisites as Messaging AI Assistants.
- Verified number support: Works with 10DLC or toll-free numbers assigned to the agent.
- Automatic routing: Sends only to the caller’s number, from the agent’s assigned number.
- Portal workflow: Prompts users to add a number if the assistant has none.
Why it matters
- Reduces external integration work for SMS actions.
- Simplifies agent design by using consistent messaging rules.
