Power your India contact center with AI Voice Agents on Exotel

Bring ElevenLabs Conversational AI to one of India's largest cloud telephony platforms. This WebSocket-based integration connects ElevenLabs AI agents directly to Exotel's voice infrastructure — no SIP provisioning, no lengthy compliance overhead, just a fast path to production.

Unlike SIP-based setups, the WebSocket approach eliminates the additional documentation and onboarding steps typically required with Exotel, letting you go live faster. Your existing Exotel numbers (ExoPhones) work immediately, and no number import is needed on the ElevenLabs side.

Key capabilities:

WebSocket-based integration for faster setup compared to SIP trunking
No number import required on ElevenLabs — connect directly via Exotel's Voicebot applet
No residency restriction — TRAI regulations do not mandate WebSocket calls to be hosted in India
Inbound and outbound call support — outbound calls triggered via Exotel API or campaign dashboard
Human transfer support via the /connect endpoint and Exotel's programmable connect applet
One-click server deployment with ready-made AWS and GCP setup scripts

What problems it solves:

Bypasses the complexity of SIP trunk provisioning with Exotel
Enables rapid deployment of AI voice agents on India's largest cloud telephony network
Provides consistent 24/7 voice automation without scaling headcount
Supports seamless handoff to human agents when needed
