Outbound Calls

The Outbound Calls connection enables your Duvo agents to place and manage phone calls to vendors, partners, and internal contacts as part of automated workflows. Powered by ElevenLabs Conversational AI and Twilio, agents can dial numbers, follow dynamic call scripts, capture outcomes, and update your systems automatically.

Capabilities

Place outbound phone calls — Automatically dial vendors, partners, and internal contacts using an ElevenLabs voice agent and a Twilio phone number. Optionally override the agent’s first message and prompt per call.
Run text-based agent conversations — Start a synchronous text conversation with an ElevenLabs agent without placing a phone call, useful for testing scripts or gathering information without voice.
Monitor call status — Track call progress in real time with status polling (in progress, completed, failed, no answer).
Retrieve call transcripts — Access the full conversation transcript after a call completes for audit trails and downstream processing.
List and inspect voice agents — Browse all ElevenLabs agents in your account and view details for a specific agent to choose the right one for each call.
List available phone numbers — See which phone numbers are available for outbound calls so agents can select or verify the correct caller ID.
