Meeting Room TV (Auto Attendant)

Meeting Room TV turns the in-room television into a calendar-driven video join screen for conference rooms. It complements the room display outside the door: employees walk in, see what is on the calendar, and join Microsoft Teams, Google Meet, or Zoom without dialing codes on a laptop.

The product ships as a Chrome Web Store extension (Auto Attendant) installed on a PC or Chromebox connected to the room TV. Microsoft Edge can run the same extension via Edge's Install extensions from other stores setting (Chrome Web Store source). Create a separate Meeting Room TV display in the admin portal — it gets its own display key, even when it reads the same room calendar as your door display. Pricing is $9/month or $99/year per room — same unit as room displays. See Pricing and billing.

Overview

Meeting Room TV is an in-room experience, not a lobby overview board. For multi-room availability in reception areas, use status boards.

Typical setup pairs one licensed room display (door) with one licensed Meeting Room TV (inside the room). Each is a separate display in Admin with its own display key and room licence — commonly $9 + $9 per month for the pair. Both usually point at the same room calendar resource.

Branding and behavior (background, room message, auto-join toggles, remote layout) are configured in extension Settings on the room computer. IT can also manage each TV display remotely from the admin portal — push configuration (including Advanced JSON that syncs when the device is online), set notification contacts, and receive alerts when Teams, Meet, or Zoom sign-in is lost on the room PC. Extension updates are delivered through the Chrome Web Store (Chrome auto-updates; Edge uses the same package when installed from other stores). Meeting Room TV does not use the door-display theme editor or walk-up booking tabs.

Why a Chrome extension?

Meeting Room TV is a Chromium browser extension (Auto Attendant) — not a separate video app and not a replacement for Microsoft Teams, Google Meet, or Zoom.

Think of it as three add-ons on top of the conferencing software you already use:

When someone joins, the extension opens the same vendor-supported browser experiences your organization already standardizes on (teams.microsoft.com, meet.google.com, Zoom in Chromium). Meeting Room 365 automates pre-join steps and exposes simple in-room controls — it does not ship a custom video stack or third-party client that might lag behind vendor features.

That design keeps full platform fidelity (layouts, security updates, certifications) while helping rooms start on time without fiddling with URLs, meeting codes, or pre-join dialogs. Employees still end up in real Teams and Meet calls; the extension just gets them there reliably from a locked-down room PC.

Supported video platforms

Full in-room automation

These platforms have dedicated join flows, optional auto-join and auto-close, and remote mic/camera/end controls:

Zoom requires the room PC to be signed in to Zoom with join from browser enabled — the extension cannot join if the account is signed out or browser join is blocked.

Other meeting links (manual join)

When a calendar event includes a join URL for Webex, BlueJeans, Jitsi, or similar providers, the idle screen can show a Join button that opens that link in the browser. That is manual join only — no deep integration. There is no auto-join, auto-close, in-call remote, or start-a-meeting-now automation for these platforms.

Calendar connections

Meeting Room TV displays are created separately in Admin and receive a new display key. They connect to the same calendar backends as room displays (usually the same room resource mailbox as the door display), except Dibs (no external calendar) is not offered in the TV setup flow:

Most customers connect Microsoft 365 or Google Workspace room calendars. Exchange can work when join URLs appear in calendar events (the extension checks several event fields), but it is a niche scenario — Zoom on Exchange is the most likely edge case, not a typical enterprise path.

For connection prerequisites (resource mailboxes, application permissions, EWS allowlisting), see Calendar connections. Microsoft 365 tenants may need a one-time PowerShell step so meeting subjects and join URLs appear correctly — the admin onboarding flow surfaces this when applicable.

Auto-join, auto-close, and idle behavior

Idle screen

The extension replaces the browser New Tab page with the Meeting Room TV cover screen:

• Shows current and upcoming meetings from the room calendar
• Refreshes calendar data every few minutes; the on-screen clock and cards update continuously
• Custom background, room message, and English or Spanish UI text (extension Settings)
• Optional PIN lock after inactivity

Auto-join

When enabled per platform in extension Settings → Platforms, the extension joins the meeting automatically at the scheduled start time. Each platform (Teams, Meet, Zoom) has its own toggle. Auto-join is off by default until you turn it on.

Auto-close

When enabled, the extension ends the call when the calendar event ends and returns to the idle cover screen. Teams and Meet content scripts also return to the cover when someone hangs up manually.

Notifications (optional)

Browser notifications and sounds can fire five minutes before a meeting starts or ends, and 30 seconds before auto-close — useful when auto-join is on and the room should be empty before the next booking.

Start a meeting now

When enabled per platform in extension Settings, the idle screen shows Start a meeting now buttons for Microsoft Teams, Google Meet, and Zoom. Tap to spin up an ad-hoc call in the official web client — useful when the room is free and no calendar event exists.

Other optional behaviors

Configured in extension Settings on the device:

• Join Teams or Meet by meeting code
• Auto-admit waiting participants (Teams / Meet)
• Hide Teams navigation bars; override Teams or Meet layout modes
• Wireless screenshare via mr365.tv — open a short URL on a laptop in the room to push your screen to the TV instantly (not a call replacement or cloud remote)

Local touchscreen remote

The remote is a second browser window on room hardware — not a phone app or cloud dashboard.

During setup, the Getting Started wizard offers no remote (automation only) or local touchscreen remote.

Recommended layout: TV on the primary display (fullscreen idle + call), touchscreen on the secondary display for remote controls.

Touch controller options

PC placement drives which option is practical: a Mimo at the table needs a USB run within about 5 m (16 ft) from the PC (or a powered hub home-run). Spacedesk avoids that cable but depends on room Wi‑Fi quality.

For cable lengths, PC placement (behind TV vs credenza vs AV closet), HDMI limits, and USB hub layouts, see the hardware selection guide.

Setup

Admin portal

1. Sign in at admin.meetingroom365.com.
2. Click New Display → Meeting Room TV (not your existing door display).
3. Choose Microsoft 365, Google Workspace, or Exchange and connect the room resource calendar for that conference room.
4. Save the new display key generated for this TV display — it is different from your door display key.

Meeting Room TV does not expose the door-display theme or walk-up booking tabs. Use extension Settings on the room PC for day-to-day options, or edit the Advanced tab in Admin to push JSON configuration to the device (same pattern as other display types). Contact support if you need help with Advanced edits.

Room computer

1. Connect a PC or Chromebox to the room TV with your chosen USB or Bluetooth camera and microphone.
2. Install the Meeting Room 365 Auto Attendant extension from the Chrome Web Store in Google Chrome. On Microsoft Edge, enable Allow extensions from other stores, then install the same listing from the Chrome Web Store.
3. Complete the Getting Started wizard: sign in to Teams, Meet, and/or Zoom on that device, then enter the Meeting Room TV display key from Admin (not the door display key).
   • Teams and Meet: one service user can sign in across all room PCs — you do not need a separate Teams or Meet login per room.
   • Zoom: each room device needs its own Zoom sign-in (often a dedicated room or service account per room).
   • Use a service account, not a personal account, on shared hardware.
4. Open extension Settings to set auto-join, remote display, background, notifications, and platform options.
5. Configure fullscreen / kiosk lockdown for production — see the hardware selection guide for Windows, ChromeOS, and enterprise policy options.

Do not open a Meeting Room TV display key in the Meeting Room 365 tablet kiosk app — TV keys require the Auto Attendant extension in Chrome (or Edge with other-stores install).

Enterprise deployment

IT teams can force-install the Chrome Web Store extension via Chrome enterprise policy (or Edge policy when the extension is sourced from other stores) and pre-provision the display key (calkey) so room PCs skip manual wizard entry. ChromeOS kiosk and managed Windows deployments are common production paths. Extension updates roll out through the Chrome Web Store. See the hardware selection guide and Meeting Room TV marketing page.

Hardware and deployment

Use hardware you already own: mini-PC, Chromebox, TV or projector, and standard USB/Bluetooth AV peripherals. No proprietary room system is required.

Project planning: decide early whether the room PC sits behind the TV, in the credenza, or in an AV closet — that drives HDMI and USB cable lengths. Prefer wired Ethernet, HDMI, and USB (camera, speaker, Mimo touch panel). Spacedesk on a tablet is the wireless alternative for the table remote. See the hardware selection guide for distances, hubs, and example room layouts.

Supported / not supported

Best fit for

• Conference rooms with a TV and PC where employees join Teams, Meet, or Zoom daily
• Organizations that already use Meeting Room 365 room displays and want a matching in-room join experience
• IT teams avoiding proprietary video appliances — standard PC, browser, and peripherals
• Touch-friendly rooms — fullscreen TV plus a local remote panel for mic/camera without a keyboard

Frequently asked questions

How much does Meeting Room TV cost?
$9/month or $99/year per room, same as a room display. A door display plus in-room TV in one conference room is typically two room licences. See Pricing and billing.

What hardware do I need?
A computer connected to the TV (PC or Chromebox), USB camera and speakerphone, and optionally a Mimo USB touch panel or Spacedesk tablet for the table remote. Plan PC placement and cable runs before install. See the hardware selection guide.

Which video platforms work?
Microsoft Teams, Google Meet, and Zoom have full join, auto-join, auto-close, and remote controls. Webex, BlueJeans, Jitsi, and similar providers support manual join only — if a join URL is in the calendar event, the idle screen offers a button to open it; there is no deeper integration.

Can I use the tablet app instead of the extension?
No. Meeting Room TV display keys require the Auto Attendant Chrome Web Store extension on the room computer (Edge: install from other stores).

How is the TV display managed remotely?
From the admin portal: open the Meeting Room TV display to edit settings, push Advanced JSON configuration to online devices, and set error notification email for alerts when Teams, Meet, or Zoom sign-in is lost on the room PC. Day-to-day toggles (auto-join, background, remote) can also be changed on the device or pushed via config sync.

Where do extension updates come from?
The Chrome Web Store. Chrome auto-updates the extension; Edge receives the same updates when the extension is installed from other stores.

Why is it a browser extension instead of its own video app?
So rooms use the official Teams, Meet, and Zoom web clients your vendor supports — with full feature fidelity — while Meeting Room 365 adds the idle screen, join automation, and tabletop remote. It is an automation and UX layer on top of your existing video stack, not a replacement for it. No third-party meeting client to certify, patch, or keep feature-parity with Microsoft and Google.

Do I sign into Teams / Meet / Zoom on the room PC?
Yes — during the Getting Started wizard or before go-live. For Microsoft Teams and Google Meet, a single service user can stay signed in across multiple rooms (same account on every room PC). Zoom is per device — each room needs its own Zoom session. Never use personal credentials on shared room hardware.

What is auto-join?
When enabled for a platform, the extension opens and joins the calendar meeting at the scheduled start time, then returns to the idle screen when the meeting ends (if auto-close is on) or when the call is ended.

Is the remote control a phone app?
No. It is a local second window on room hardware — typically a touchscreen beside the TV.

Can I customize branding in Admin?
Day-to-day options (background, room message, auto-join) are in extension Settings on the room PC. IT can also push updates via the display Advanced tab in Admin — JSON changes sync to the extension when the device is online. There is no door-display-style theme editor for TV.

Does it work with my existing door display?
Yes — as a companion product for the same conference room. You still create a new Meeting Room TV display in Admin (with its own display key and licence). It typically connects to the same room calendar as the door display, but the TV and door are separate displays.

Do I reuse my door display key on the TV?
No. Enter the Meeting Room TV display key in the Auto Attendant extension. Door display keys load the tablet kiosk app, not Meeting Room TV.

Chrome or Edge?
The extension is published on the Chrome Web Store only. Use Google Chrome, or Microsoft Edge with Allow extensions from other stores enabled, then install from the same Chrome Web Store listing.

I'm on Exchange — any caveats?
Exchange is available in the TV setup flow, but most organizations use Microsoft 365 or Google Workspace. On Exchange, whether join buttons appear depends on how meeting URLs are stored in calendar events — Zoom on Exchange is the most common niche that works. Contact support if you are evaluating an Exchange-only deployment.

What is wireless screenshare?
Optional mr365.tv screenshare: when enabled, the idle screen shows a room code. Someone standing in the room opens mr365.tv/<code> on a laptop and shares their screen to the TV — handy for quick presentations, not a replacement for Teams/Meet/Zoom or the tabletop remote.
