Exotel voice AI
Exotel voice AI on the numbers you already have.
Exotel runs calling and contact-centre infrastructure for businesses across India, the Middle East, Africa and Asia-Pacific. If your business numbers already live there, you do not have to move them to put an AI voice agent on the line.
VocalLabs connects to your Exotel account. Import your DIDs, point inbound calls at a published agent, and place outbound calls one at a time or as a scheduled batch. Exotel keeps the numbers and the call billing; VocalLabs runs the agent.

How an Exotel number reaches a VocalLabs agent.
Four moves: connect the account, import your DIDs, assign a published agent, and call out when you need to. The phone network stays Exotel’s; the conversation runs on VocalLabs.

- 02Phone Numbers in VocalLabsConnect the account and import your DIDs.
- 03A published agentAssigned to answer inbound calls on the number.
- 04The conversationYour prompt, tools and models, on your own keys.
- 05On the recordRecording, transcript, tool calls and post-call analysis.
- Inbound
- Assign a published voice agent to an imported number and it answers the calls that number receives.
- Outbound
- Place calls one at a time or as a scheduled batch, from the dashboard or the API. The same published agent answers inbound.
- Numbers on a contact-centre platform
- If a contact-centre platform already holds your numbers, it can stream call audio to the agent over a WebSocket instead.
