Product Overview

A communication base, not an AI application.

Hotel AI switchboard projects usually combine two very different disciplines: AI conversation design and local telephony. Vanttel delivers the second one—an EdgePBX edge communication host and a set of hotel-specific IP phones—so solution providers do not have to build a SIP PBX or adapt hotel handsets from scratch.

EdgePBX handles call control, SIP trunks, extensions, media and phone management. It exposes call events, key presses, hook states and lamp states to your AI platform, and accepts commands to transfer calls, play prompts or change phone lamps.

Your AI platform keeps ownership of ASR / TTS, dialogue strategy, guest reception logic, intent recognition and hotel service workflows. Vanttel does not store or interpret business semantics.

Boundary statement: Vanttel does not provide AI voice applications. This page describes the communication transport layer only; AI recognition accuracy, dialogue completion and guest experience are determined by the solution provider's own platform.

01 / Architecture

Layered by design. Clear responsibility.

The communication base is decoupled from the AI application. Solution providers focus on dialogue and hotel workflows while Vanttel carries call control, terminals and local survivability.

LAYER 01 AI Switchboard Application Voice and business logic built or purchased by the provider. Partner · own AI platform
ASR / TTS engines Dialogue orchestration Guest reception logic Intent recognition Hotel service workflows

Runs on the provider's own AI platform and does not depend on the Vanttel base.

LAYER 02 EdgePBX Edge Communication Base Call transport, phone management, signalling and media. Delivered by Vanttel
SIP switching Call control Internal / external trunks Extension management Phone management Event callbacks Local high availability

Exposes events and control interfaces upward, and is the only layer directly connected to terminals and outside lines.

LAYER 03 Hotel IP Phone Terminals Hardware capabilities exposed as standard signals. Delivered by Vanttel
Guest room phones Reception consoles Security / dispatch phones BLF indicator lamps Custom function keys

Key presses and lamp states are abstracted into standard signals that the AI application can call directly.

LAYER 04 Hotel Business Systems Optional integration decided by the AI application. Partner · project scope
Hotel PMS Room control RCU Access control Alarm panels

EdgePBX publishes events and interfaces; business orchestration for external systems stays in the upper layer.

Division of labour: AI dialogue, intent recognition and business decisions all run inside the provider's AI application. EdgePBX performs call infrastructure only and does not store or interpret business semantics.

A

Standard SIP Integration

The provider's AI service connects to EdgePBX over standard SIP and follows a standard call flow. Compatible with mainstream AI call engines, softswitches and media servers.

SIPMEDIA SERVERSTANDARD CALL FLOW
B

Event Callback Integration

EdgePBX pushes call state, key presses, hook states and room signals to the provider platform through Webhook / HTTP. Provider commands control transfer, playback and phone lamp states.

WEBHOOKHTTP APIEVENT PUSH
02 / EdgePBX

EdgePBX edge communication host.

A hotel-specific edge SIP host for AI switchboard providers, with built-in hotel phone signal abstraction and open interfaces for fast upper-layer integration.

Core SIP Communication

Standard PBX call transport for hotel internal and external scenarios.

  • Internal and external trunk access with call routing
  • Call queueing, transfer, hold and multi-party calls
  • Call recording, voicemail and media forwarding
  • Runs locally, keeping internal calls available during a WAN outage

Native Hotel Signals

Hotel phone hardware capabilities abstracted into standard events.

  • Off-hook, on-hook, key press and DTMF events
  • BLF, do-not-disturb and wake-up lamp states
  • Extension and call events pushed to the upper platform in real time
  • Ready for AI-driven judgement and hotel workflow orchestration

Open Interfaces

Standard protocols, event callbacks and management APIs—no AI platform lock-in.

SIP Standard connection to AI engines and media servers
Webhook Call start, ringing, answer, hang-up and state changes
HTTP API Extension management, configuration, lamp control, transfer, playback and barge-in

Media streams can be forwarded to the provider's own media service.

01
Appliance Pre-installed EdgePBX system, ready to deploy on site.
02
Embedded Edition Can be imported into the provider's own hardware platform.
03
Chain Mode Local deployment per property, with remote management of hosts and phones.

Capability boundary: EdgePBX does not include an AI dialogue engine or hotel business workflows. It provides call infrastructure only; speech recognition, dialogue strategy and room service orchestration are delivered by the upper-layer provider solution.

03 / Terminals

Hotel-specific IP phone terminals.

Natively adapted to EdgePBX. Keys, lamps and hardware capabilities are open to the AI application, with hotel interaction templates pre-installed—no firmware redevelopment required.

Open Hardware Capabilities Custom keys and lamps can map to AI business logic without changing phone firmware.
04 / Why Vanttel

Why AI switchboard providers choose this base.

Avoid duplicated investment in PBX and terminal adaptation. Vanttel carries communication stability while the provider focuses on AI value.

01

Clear separation of duties

The provider owns AI dialogue and hotel workflows; Vanttel owns SIP transport, terminals and phone management.

02

Native hotel hardware adaptation

Guest room keys, status lamps and emergency signals are exposed as standard interfaces, removing terminal integration work.

03

Local high availability

Internal calls and phone links keep working when the WAN is interrupted—the stability risk most often exposed in hotel projects.

04

Standard open interfaces

SIP, Webhook and HTTP APIs avoid vendor lock-in and connect to any self-developed or third-party AI engine.

05

Complete hardware supply

Hosts and phones are delivered as a matched kit for project supply, with OEM / white-label options available on discussion.

06

Hotel scenario presets

Guest room, reception and security call models are built in—not retrofitted from a generic PBX—reducing adaptation effort.

05 / Deployment

Reference deployment topologies.

Two common models: a single property with a local closed loop, or a chain with local EdgePBX per property and centralized AI at headquarters.

LOCAL LOOP / CENTRALIZED AI

Single property integration

EdgePBX and hotel IP phones are deployed on the property network; the AI service connects locally or from the cloud.

06 / Responsibility Matrix

Who owns what in the project.

A practical split between the Vanttel communication base and the provider's AI application. Project-specific items are confirmed during solution design.
