+# UBK Intercom Setup - Mumble/Talkkonnect
+
+This is a standalone script for setting up push-to-talk (PTT) intercom functionality for the Ubuntu Based Kiosk using Mumble/Talkkonnect.
+
+## How to Use
+
+### Option 1: Via Main Install Script (Recommended)
+If you've cloned or downloaded the UBK repository, the intercom setup is automatically available:
+
+```bash
+# Run the main UBK installer
+./install_kiosk_0.9.6.sh
+
+# Navigate to: Main Menu → Addons Management (option 2)
+# Then select: talkkonnect/Murmur Intercom (native audio) (option 4)
+```
+
+The main installer will automatically launch `setup_intercom.sh` when you select the intercom option.
+
+### Option 2: Standalone Usage
+You can also run the intercom setup script directly:
+
+```bash
+# Make sure both scripts are in the same directory
+cd /path/to/ubk
+./setup_intercom.sh
+```
+
+**Important:** Both `install_kiosk_0.9.6.sh` and `setup_intercom.sh` must be in the same directory for the integration to work.
+
+## What's Included When You Download the Repository
+
+When you clone or download the UBK repository, you get:
+
+```
+ubk/
+├── install_kiosk_0.9.6.sh      # Main UBK installer (has intercom integration)
+├── setup_intercom.sh           # Standalone intercom setup & management
+├── INTERCOM_README.md          # This file
+└── integrate_intercom.sh       # (Optional) Integration helper/documentation
+```
+
+Both scripts work together:
+- **install_kiosk_0.9.6.sh**: Full UBK installation with integrated intercom support
+- **setup_intercom.sh**: Dedicated intercom setup with its own menu system
+
+You don't need to modify anything - just run either script and they'll find each other automatically.
+
+## Overview
+
+The intercom system uses:
+- **Murmur**: The Mumble server software (can run on one kiosk)
+- **talkkonnect**: A headless Mumble client optimized for push-to-talk
+
+## Use Cases
+
+### 1. All-in-One (Server + Client)
+One kiosk acts as both the server and a client. Other devices can connect to it.
+
+```bash
+./setup_intercom.sh
+# Select option 1: Install All-in-One (Server + Client)
+```
+
+### 2. Client Only
+Connect to an existing Mumble server (could be another kiosk or external server).
+
+```bash
+./setup_intercom.sh
+# Select option 3: Install talkkonnect Client Only
+# Enter the server IP, port, and credentials
+```
+
+### 3. Server Only
+Turn a kiosk into a dedicated Mumble server.
+
+```bash
+./setup_intercom.sh
+# Select option 2: Install Murmur Server Only
+```
+
+## Quick Start
+
+### Single Kiosk Setup (Server + Client)
+
+```bash
+cd /path/to/ubk
+./setup_intercom.sh
+```
+
+1. Select **Option 1: Install All-in-One (Server + Client)**
+2. Set a SuperUser password (for server administration)
+3. Set a server password (clients need this to connect)
+4. Set a welcome message
+5. Set a username for the talkkonnect client
+6. The client will auto-connect to the local server
+
+### Multi-Kiosk Setup
+
+**On the server kiosk:**
+```bash
+./setup_intercom.sh
+# Select option 2: Install Murmur Server Only
+# Note the server IP address shown after installation
+```
+
+**On each client kiosk:**
+```bash
+./setup_intercom.sh
+# Select option 3: Install talkkonnect Client Only
+# Enter the server IP from above
+# Port: 64738 (default)
+# Enter username and password
+```
+
+## Features
+
+### Push-to-Talk
+- Default PTT key: **Spacebar**
+- Press and hold to transmit audio
+- Release to stop transmitting
+
+### Management
+The script provides a full-featured menu for:
+- Starting/stopping services
+- Reconfiguring settings
+- Viewing logs
+- Uninstalling components
+
+### Connecting from Other Devices
+
+Other devices can connect to your Mumble server using:
+
+**Desktop (Windows/Mac/Linux):**
+- Download Mumble client: https://www.mumble.info/downloads/
+- Connect to: `<kiosk-ip>:64738`
+
+**Mobile (iOS/Android):**
+- Install Mumble app from app store
+- Add server: `<kiosk-ip>:64738`
+
+## Configuration
+
+### Server Configuration
+Location: `/etc/mumble-server.ini`
+
+Key settings:
+- Port: 64738 (default)
+- Max users: 10
+- Bandwidth: 72000
+
+### Client Configuration
+Location: `/home/kiosk/talkkonnect.xml`
+
+Key settings:
+- Server address and port
+- Username and password
+- PTT button (default: spacebar)
+- Audio settings
+
+## Troubleshooting
+
+### Check Service Status
+
+```bash
+# Check Murmur server
+sudo systemctl status mumble-server
+
+# Check talkkonnect client
+sudo systemctl status talkkonnect
+```
+
+### View Logs
+
+Use the built-in menu options, or:
+
+```bash
+# Murmur logs
+sudo journalctl -u mumble-server -n 50
+
+# talkkonnect logs
+sudo journalctl -u talkkonnect -n 50
+```
+
+### Audio Issues
+
+1. Check audio devices:
+```bash
+arecord -l  # List recording devices
+aplay -l    # List playback devices
+```
+
+2. Test audio:
+```bash
+# Test microphone
+arecord -d 5 test.wav && aplay test.wav
+```
+
+3. Edit talkkonnect configuration:
+```bash
+nano /home/kiosk/talkkonnect.xml
+# Adjust <audio> section device names
+sudo systemctl restart talkkonnect
+```
+
+### Firewall
+
+If clients can't connect, ensure port 64738 is open:
+
+```bash
+sudo ufw allow 64738/tcp
+sudo ufw allow 64738/udp
+```
+
+## Integration with Main Install Script
+
+To integrate this into the main UBK install script:
+
+### Option 1: Direct Integration
+
+Add to the addon menu in `install_kiosk_*.sh`:
+
+```bash
+# In the addon menu section
+echo "  X. Intercom (Mumble/Talkkonnect)"
+
+# In the case statement
+X)
+    # Source and run the intercom script
+    bash setup_intercom.sh
+    ;;
+```
+
+### Option 2: Call as External Script
+
+```bash
+# From anywhere in the install script
+if [[ -f "$SCRIPT_DIR/setup_intercom.sh" ]]; then
+    bash "$SCRIPT_DIR/setup_intercom.sh"
+else
+    echo "Intercom setup script not found"
+fi
+```
+
+### Option 3: Function Import
+
+Source the functions for use in the main script:
+
+```bash
+# Source the intercom functions (requires extracting functions to separate file)
+source "$SCRIPT_DIR/intercom_functions.sh"
+
+# Then call functions directly
+install_murmur_and_talkkonnect
+```
+
+## Technical Details
+
+### Murmur Server
+- Package: `mumble-server`
+- Service: `mumble-server.service`
+- Port: 64738 (TCP/UDP)
+- Config: `/etc/mumble-server.ini`
+- Database: `/var/lib/mumble-server/mumble-server.sqlite`
+
+### talkkonnect Client
+- Written in: Go
+- Built from: https://github.com/talkkonnect/talkkonnect
+- Binary: `/home/kiosk/go/bin/talkkonnect`
+- Service: `talkkonnect.service`
+- Config: `/home/kiosk/talkkonnect.xml`
+
+### Dependencies
+- Go 1.23.4+
+- libopenal-dev
+- libopus-dev
+- alsa-utils
+- portaudio19-dev
+- git
+
+## Network Requirements
+
+- **Server**: Port 64738 (TCP/UDP) must be accessible
+- **Clients**: Outbound access to server on port 64738
+- **Local Network**: For LAN-only intercom, no internet required
+- **Remote Access**: If connecting over internet, configure port forwarding
+
+## Security Considerations
+
+1. **Server Password**: Set a strong server password to prevent unauthorized access
+2. **SuperUser Password**: Keep this secure - it has admin privileges on the server
+3. **Network**: Consider using a VPN for remote access instead of exposing port 64738 to the internet
+4. **Certificates**: For production, consider setting up SSL/TLS certificates (currently using `insecure: true`)
+
+## Version History
+
+- **v1.0.0** - Initial standalone release
+  - Full Murmur server installation
+  - talkkonnect client installation
+  - All-in-one option
+  - Service management
+  - Configuration tools
+
+## Support

+################################################################################
+#
+# RELEASE v0.9.6 - WebRTC Intercom System
+#
+# What's NEW in v0.9.6:
+# - NEW: Built-in WebRTC intercom system with push-to-talk
+#   * Auto-discovery: Kiosks automatically find each other via mDNS (no configuration!)
+#   * Browser-based phones: No app installation - just open URL in Chrome/Safari
+#   * Smart conversations: Responses auto-route back to caller (60s timeout)
+#   * Selective communication: Choose which kiosk/phone to talk to
+#   * Media key PTT: Uses Mute or PlayPause key (doesn't trigger page navigation)
+#   * Lock screen aware: Configurable intercom behavior when kiosk is locked
+#   * Zero external dependencies: WebSocket signaling + WebRTC audio embedded in Electron
+#   * Dynamic expansion: Add new kiosks anytime - they auto-discover existing ones
+# - NEW: Progressive Web App (PWA) client for phones/tablets
+#   * Single-file HTML served from kiosk
+#   * Works on Android and iOS (Chrome, Safari)
+#   * Push-to-talk button with visual feedback
+#   * Shows available kiosks in real-time
+#   * Can be added to home screen
+# - NEW: Kiosk-to-kiosk intercom
+#   * Full mesh network for 1-5 kiosks
+#   * Auto-elected hub for 6+ kiosks
+#   * Topology adapts automatically
+# - NEW: Target selection overlay
+#   * Keyboard navigation (arrow keys) or touch
+#   * Hold PTT >1 second to change target mid-conversation
+#   * Shows online/offline status for each endpoint
+# - CONFIGURATION: Simple 4-question setup during install
+#   * Friendly name (e.g., "Kitchen", "Office")
+#   * PTT key choice (Mute or PlayPause)
+#   * Lock screen behavior (Allow/Disable/Receive-only)
+#   * Response mode (Caller-only or Broadcast)
+# - TECHNICAL: Phone-initiated calls work everywhere
+#   * Kiosk-initiated calls work when phone PWA is open
+#   * PWA limitation: phones can't receive calls when app is closed (browser restriction)
+#   * Future: Can add wake locks or push notifications if needed
+# - All fixes from v0.9.5-12 included
+#
+# RELEASE v0.9.5-12 - Site-Specific Extension Fix
+#
+# What was in v0.9.5-12:
+# - CRITICAL FIX: Time extensions now properly cleared on automatic rotation
+#   * ISSUE: Extensions granted on one site would persist when automatically rotating to another site
+#     Example: User gets 15-min extension on Site A, Site A's timer expires and rotates to Site B,
+#     Site B would stay paused for the remaining extension time (incorrect behavior)
+#   * ROOT CAUSE: rotateToNextSite() function didn't clear inactivityExtensionUntil
+#     Manual navigation (Ctrl+Tab, swipe) already cleared extensions, but automatic rotation didn't
+#   * FIX: Added inactivityExtensionUntil=0 in rotateToNextSite() function (line 4537)
+#     Extensions now site-specific: when navigating away (manually OR automatically), rotation resumes
+#   * BEHAVIOR: Extensions only apply to the site they were granted on
+#     If user grants 30-min extension to read a recipe, finishes in 20 min, and navigates away,
+#     the new site will rotate normally (extension doesn't follow to new site)
+# - All fixes from v0.9.5-11 included
+#
+# RELEASE v0.9.5-11 - BrowserView Attachment Fix
+#
+# What was in v0.9.5-11:
+# - CRITICAL FIX: Resolved BrowserView attachment error on password unlock
+#   * ERROR: When unlocking password screen, users received error:
+#     "Error: Given BrowserView is not attached to the window"
+#     This caused a white screen requiring Ctrl+Alt+Del → Reload to recover
+#   * ROOT CAUSE: showLockoutScreen() removes all BrowserViews (security feature)
+#     but unlockScreen() called setTopBrowserView() without first adding the view back
+#     Electron requires view to be attached before setting as top
+#   * FIX: Added mainWindow.addBrowserView() before setTopBrowserView() in attachView()
+#     function (line 4538-4544), wrapped in try-catch for already-attached cases
+# - All fixes from v0.9.5-10 included
+#
+# RELEASE v0.9.5-10 - Enhanced Password Lockout Security
+#
+# What's NEW in v0.9.5-10:
+# - SECURITY FIX: Browser views now completely hidden when locked
+#   * All browser views detached from mainWindow during lockout
+#   * Prevents content visibility when password screen is active
+#   * Users cannot see any URLs or content until password is entered
+# - IMPROVED: Power menu displays on solid black screen when locked
+#   * Power menu now shows on lockoutWindow instead of mainWindow
+#   * No content visible behind power menu when system is locked
+# - SIMPLIFIED: Removed time-based lockout restrictions
+#   * Eliminated "Only enforce lockout during specific hours?" prompt
+#   * Password protection now always active when enabled
+#   * More reliable and predictable security behavior
+# - All fixes from v0.9.5-9 included
+#
+# RELEASE v0.9.5-9 - CRITICAL Inactivity Lockout Fix (Simplified)
+#
+# What was in v0.9.5-9:
+# - CRITICAL FIX: Inactivity lockout now works (was never triggering)
+#   * Removed lockoutActivityTime reset from markActivity() function
+#   * markActivity() was being called on EVERY mouse move, click, keyboard press
+#   * This constantly reset the lockout timer, preventing it from ever triggering
+#   * Now lockout timer ONLY resets when user unlocks or selects time extension
+# - All fixes from v0.9.5-8 included
+#
+# ROOT CAUSE:
+# The markActivity() function (line 3904-3906) was resetting lockoutActivityTime:
+#   markActivity(){
+#     ...
+#     if(enablePasswordProtection && lockoutTimeout > 0){
+#       lockoutActivityTime = now;  // ← THIS WAS THE PROBLEM
+#     }
+#   }
+#
+# markActivity() is called on EVERY:
+# - Mouse move
+# - Mouse click
+# - Keyboard press
+# - Page load
+# - Focus change
+#
+# This meant lockoutActivityTime was CONSTANTLY being reset, so the lockout
+# timer could NEVER reach the configured timeout (e.g., 17 minutes).
+#
+# FIX:
+# Removed the lockoutActivityTime reset from markActivity() entirely.
+# Now lockoutActivityTime only resets when:
+# 1. User unlocks the screen (in unlockScreen() function)
+# 2. User selects a time extension (in showPauseDialog/showInactivityPrompt)
+#
+# This is simple and correct: lockout should trigger after X minutes of
+# inactivity, regardless of whether user is actively using the site or not.
+# Time extensions explicitly extend the lockout timer when user confirms presence.
+#
+# RELEASE v0.9.5-6 - Boot Password Sequence Fix
+#
+# What was in v0.9.5-6:
+# - Boot password now required BEFORE showing any websites
+# - Limited power menu when locked (no Reload option)
+#
+# TROUBLESHOOTING: If navigation (Ctrl+Tab, swipe) doesn't work:
+# - Check your config.json for sites with duration: -1 (hidden sites)
+# - Hidden sites don't appear in rotation and don't count toward navigation
+# - Ensure you have at least 2 visible sites (duration >= 0) for navigation to work
+# - Run the install script menu option 1 to view current configuration
+#
+# RELEASE v0.9.5-4 - CRITICAL Security and Compatibility Fixes
+#
+# What was in v0.9.5-4:
+# - CRITICAL SECURITY FIX: Restricted polkit permissions to prevent Ctrl+Alt+Del bypass
+#   * Changed org.freedesktop.login1.* (ALL actions) to specific power operations only
+#   * Prevents session switching and VT access that could bypass kiosk security
+# - CRITICAL SECURITY FIX: Added X server ServerFlags to block VT switching
+#   * Disabled Ctrl+Alt+F1-F12 VT switching with DontVTSwitch option
+#   * Disabled Ctrl+Alt+Backspace X server kill with DontZap option
+#   * Added AllowClosedownGrabs protection
+# - SECURITY: Enhanced LightDM greeter security settings
+#   * Hide user list, disable manual login, disable guest account
+# - FIXED: Autostart script compatibility errors ([[: not found)
+#   * Converted bash-specific [[ ]] syntax to POSIX-compliant [ ] syntax
+#   * Fixed all conditional tests in display schedule and quiet hours logic
+# - FIXED: xbindkeys errors (missing .xbindkeysrc)
+#   * Now creates empty .xbindkeysrc file to prevent xbindkeys startup errors
+#
+# RELEASE v0.9.5-3 - Extension and Manual Navigation Fixes
+#
+# What was in v0.9.5-3:
+# - CRITICAL FIX: Time extensions now work correctly (15 min actually = 15 min)
+#   * Removed inactivityExtensionUntil=0 from markActivity() function
+#   * Extensions no longer cleared by clicking extension buttons
+#   * Pause button extensions now work for full selected duration
+#   * Manual site timeout extensions now work for full selected duration
+# - FIXED: Manual tab switching now clears extensions appropriately
+#   * Ctrl+Tab, Ctrl+Shift+Tab, swipe gestures now clear active extensions
+#   * Prevents confusion when user manually navigates during extension
+#
+# RELEASE v0.9.5-2 - Settings Persistence & Timing Fixes
+#
+# What was in v0.9.5-2:
+# - CRITICAL FIX: Sites no longer wiped when editing password/pause/OSK settings
+#   * Added load_existing_config() to preserve all settings before save
+#   * Fixed empty URLS/DURS arrays from overwriting sites in config.json
+# - CRITICAL FIX: Password protection now properly saved/persists on reboot
+# - CRITICAL FIX: Sites now properly saved/persist on reboot
+# - FIXED: Time extension now works on correct site (not next rotation site)
+#   * Pause dialog blocks rotation while user is selecting time
+#   * Inactivity prompt blocks rotation while user is responding
+# - FIXED: Pause button now properly blocks rotation for selected duration
+# - FIXED: Manual site timeout popup no longer appears 1 min after extension expires
+#   * Extension expiration now properly resets lastUserInteraction timer
+# - NEW: Cancel/exit option in password and optional features menus
+#   * Menus now ask "Save these changes?" before applying
+#   * Answer "no" to discard changes without affecting config
+# - ENHANCED: Comprehensive settings display on main menu
+#   * Shows all sites with [HOME] marker
+#   * Shows home URL and inactivity timeout
+#   * Shows pause/keyboard button status
+#   * Shows complete password protection configuration
+#
+# RELEASE v0.9.5-1 - Lockout Stay Locked Fix
+#
+# What was in v0.9.5-1:

+### Integration Helper for Intercom Setup
+################################################################################
+#
+# This script shows how to integrate the standalone intercom setup
+# into the main UBK install script.
+#
+# Usage:
+#   1. Copy this code block into your main install script
+#   2. Add a menu option to call launch_intercom_setup()
+#   3. The intercom setup will run as a subshell and return control
+#
+################################################################################
+
+# Get the directory where scripts are located
+SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+
+launch_intercom_setup() {
+    local intercom_script="$SCRIPT_DIR/setup_intercom.sh"
+
+    if [[ ! -f "$intercom_script" ]]; then
+        echo "[ERROR] Intercom setup script not found at: $intercom_script"

+        return 1
+    fi
+
+    # Make sure it's executable
+    chmod +x "$intercom_script"
+
+    # Launch the intercom setup
+    bash "$intercom_script"
+
+    # Return code will be passed through
+    return $?

+#         echo "  6. Mumble/Talkkonnect Intercom"  # <-- Add this line
+#         echo "  0. Return to main menu"

+#             6) launch_intercom_setup ;;  # <-- Add this line
+#             0) return ;;
+#         esac
+#     done
+# }
+
+################################################################################
+### Alternative: Direct Function Call
+################################################################################
+
+# If you want even tighter integration, you can source the intercom script
+# and call its functions directly. This requires modifying setup_intercom.sh
+# to check if it's being sourced or run directly:
+#
+# In setup_intercom.sh, replace the main entry point section with:
+#
+# if [[ "${BASH_SOURCE[0]}" == "${0}" ]]; then
+#     # Script is being run directly
+#     main_menu
+# fi
+#
+# Then you can source it:
+#
+# source "$SCRIPT_DIR/setup_intercom.sh"
+# install_murmur_and_talkkonnect  # Call functions directly
+

+# This script provides a complete push-to-talk (PTT) intercom solution using:
+#   - Murmur: The Mumble server (can run on one kiosk)
+#   - talkkonnect: A headless Mumble client for push-to-talk communication
+#
+# Use Cases:
+#   1. Server + Client (All-in-one): One kiosk acts as both server and client
+#   2. Client Only: Connect to an existing Mumble server
+#   3. Server Only: Set up a kiosk as the intercom server
+#
+# Other kiosks or devices can connect using:
+#   - talkkonnect (Linux)
+#   - Mumble desktop client (Windows/Mac/Linux)
+#   - Mumble mobile app (iOS/Android)
