Created modular, standalone intercom system to avoid bloating the
10,000+ line main install script.

New Files:
- setup_intercom.sh: Complete standalone installation and management
  * Install Murmur server (one kiosk becomes the server)
  * Install talkkonnect client (connect to existing server)
  * Install both (all-in-one setup)
  * Full service management (start/stop/restart)
  * Configuration tools
  * Log viewing
  * Uninstall options

- INTERCOM_README.md: Comprehensive documentation
  * Quick start guide
  * Use cases and scenarios
  * Multi-kiosk setup instructions
  * Troubleshooting guide
  * Integration instructions
  * Technical details

- integrate_intercom.sh: Integration helper
  * Shows how to wire into main install script
  * Example menu integration code
  * Alternative sourcing method

Features:
✓ Menu-driven interface with dynamic options
✓ Status display (installed/running state)
✓ Server configuration (password, port, welcome text)
✓ Client configuration (server, credentials, channel)
✓ Service management (enable/disable/start/stop)
✓ Log viewing for diagnostics
✓ Clean uninstallation

Use Cases:
1. Single kiosk (server + client)
2. Multi-kiosk (one server, multiple clients)

+# 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.
+
+## 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
+

+### 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"

+        read -r -p "Press Enter to continue..."
+        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 $?
+}

+#             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
