The omnichannel communication platform for hotels, resorts, restaurants, and the full guest economy — voice, text, email, chat & WhatsApp, with sub-500ms end-to-end latency.
Every guest touchpoint and every back-of-house need — voice, messaging, email, and agents — on one brain, one architecture.
Voice AI that answers every inbound call with sub-500ms end-to-end latency — 24/7, in 40+ languages — handling reservations, requests, and dispatch like a five-star front desk.
SMS, MMS, and WhatsApp with shared inboxes that put your team and AI in the same workspace — assisted, human-led, or fully automated.
Inbox intelligence for hospitality — triage, draft, and respond automatically, or in assist mode where your team approves before sending.
Guest-facing website chat out front, plus internal staff assistants and operational AI embedded directly in Microsoft Teams and Slack.
A proprietary cascading LLM architecture routes every function call to the best frontier model for the task — fast models for fast tasks, reasoning models for concierge work, invisible to the guest.

Get Started →The omnichannel communication platform purpose-built for hospitality — voice, SMS, email, chat, and WhatsApp agents for hotels, resorts, restaurants, casinos, venues, and the full guest economy. 24/7, with no missed calls.
Four integrated products on one platform: Call Stream Voice (voice agents answering every call in under 500ms, 24/7, 40+ languages, with cascading LLM routing and Call Stream Verify); Call Stream Messaging (unified SMS, MMS & WhatsApp with shared team inboxes — assisted, human-led, or fully automated); Call Stream Email (inbox triage, intent classification, and auto-drafts grounded in your knowledge base); and Call Stream Agents (guest website chat plus internal staff assistants and operational AI in Microsoft Teams and Slack).
Every function call routes across frontier models from Anthropic, OpenAI, and Google Gemini — fast models for simple requests, reasoning models for complex concierge tasks — selected in real time for speed, accuracy, and cost, invisible to the guest.
Five channels: Voice (inbound & outbound calls), SMS & MMS, Email, Webchat (embedded on your site), and WhatsApp. All channels share the same knowledge base and guest context for a unified omnichannel experience.
Yes. Beyond guest-facing communication, the platform powers back-of-house operational intelligence — embedded directly in Microsoft Teams and Slack, giving staff instant answers from your operational knowledge base.
12 verticals across the guest economy: hotels, resorts, restaurants & dining, casinos & gaming, venues & attractions, rideshare & transportation, travel & tourism, short-term rentals, stadiums & events, spas, entertainment, and more. Each vertical has a purpose-built agent trained on industry-specific workflows.
Oracle Opera, Infor HMS, Maestro, Agilysys, HotSOS, ALICE, OpenTable, Resy, SevenRooms, Book4Time, Stripe, Toast, Slack, and Microsoft Teams — plus 3,000+ more via Pipedream MCP. A flexible REST API supports custom integrations with any hospitality system.
Yes. Call Stream AI supports multi-property routing, letting hotel groups, restaurant chains, and management companies deploy agents across all locations with centralized management and property-specific knowledge bases.
Unlike traditional phone systems with limited lines, Call Stream AI answers unlimited simultaneous calls. During peak events — New Year's Eve, Super Bowl weekend, opening night — every call is answered in under 500ms with no hold queues, busy signals, or missed revenue.
Designed with SOC 2 alignment across all five Trust Service Criteria — Security, Availability, Processing Integrity, Confidentiality, and Privacy. Every component — Twilio, AWS, Google Cloud, Supabase, Render, GitHub — is SOC 2 compliant or aligned, and every interaction is sealed by Call Stream Verify.
AI proxies are routing layers that aggregate credentials and have no memory, workflows, or execution capability. Call Stream AI is a platform — not a proxy. It integrates natively with Anthropic, OpenAI, and Google Gemini and cascades across them based on the workflow in motion. Model selection, security, and auditability are all part of execution.
Call Stream AI maintains 99.7% uptime with redundant infrastructure across AWS and Google Cloud. In the rare event of a disruption, calls automatically failover to your property's backup line — no calls are lost, even during maintenance windows.
The AI is trained on your property's specific knowledge base — menus, rates, policies, amenities — so responses are grounded in your data, not generic guesses. Edge cases escalate to your team with full context, and every interaction is logged and sealed with Call Stream Verify so you can audit any response.
It seamlessly transfers the call to your team with full context of the conversation. No dead ends — every guest interaction is handled professionally, whether by AI or your staff.
None. Call Stream AI is fully managed — our team custom-builds every agent to match your brand voice, workflows, menus, and amenities. Every deployment is tailored, not a template.
It varies by complexity. A single-property restaurant with standard integrations can be live in 1–2 weeks; a multi-property hotel group with Oracle Opera, custom workflows, and multiple departments typically takes 3–6 weeks. Every deployment is custom-built, accounting for training, integration testing, and brand-voice calibration.
