Exotel

Exotel is an Indian cloud telephony and customer-engagement (CPaaS) platform offering programmable voice, SMS, virtual numbers (ExoPhones), IVR/call flows, call campaigns, and call-center tooling. Its Twilio-style REST APIs place outbound calls (connect two numbers or connect a number to a call flow), send SMS, return call and number metadata, and manage campaigns, over region-specific subdomains (api.exotel.com for Singapore, api.in.exotel.com for Mumbai/India) using HTTP Basic auth with an API Key and API Token. Exotel AgentStream adds a documented WebSocket voice-streaming API for real-time voicebots.
