Voice Calls

Communication

Make and manage voice calls programmatically

• Initiate calls with spoken messages
• Continue conversations mid-call
• Multi-provider: Twilio, Telnyx, Plivo

What You Can Do

Initiate calls — Start voice calls with a spoken message

Continue calls — Send additional messages during active calls

Real-time speech — Text-to-speech during ongoing conversations

Call management — End calls and check status

Multi-provider — Twilio, Telnyx, Plivo, or mock (for testing)

Try Asking

"Call +1-555-0123 and say 'Your delivery has arrived'"

"Continue the call and say 'The issue has been resolved'"

"Check the status of the active call"

"End the current call"

"Make a test call using the mock provider"

Pro Tips

Mock provider lets you test call flows without real call charges

Write messages in natural spoken language — avoid abbreviations

Save call IDs from initiation to continue or end specific calls

Check status before sending follow-ups to verify connection

Ensure your from-number is verified with your provider
