To set up two ROIP-102 devices to link to radios over the internet, follow these steps:

1. Connect and Configure Each ROIP-102 Device:

   • Connect each ROIP-102 device to the respective radio and ensure they are powered on.
   • Connect each device to a network (either via Ethernet or Wi-Fi).

2. Access the Web Interface:

   • Use a computer connected to the same network as the ROIP-102 device.
   • Open a web browser and enter the default IP address of the ROIP-102 device (refer to the device manual for the default IP address).
   • Log in to the web interface using the default username and password (usually provided in the device manual).

3. Configure Network Settings:

   • Assign static IP addresses to each ROIP-102 device to ensure consistent network connectivity.
   • Configure the network settings such as gateway, subnet mask, and DNS settings according to your network infrastructure.

4. Set Up the Link between ROIP-102 Devices:

   • In the web interface, navigate to the settings for the ROIP link configuration.
   • For each device, set one as the "Master" and the other as the "Slave" (or configure both as peers if supported).
   • Enter the IP address of the remote ROIP-102 device to establish the link.
   • Configure port forwarding on your router if the devices are on different networks or behind NAT (Network Address Translation).

5. Configure Radio Interface Settings:

   • Set up the audio and PTT (Push-to-Talk) settings according to the specifications of the connected radios.
   • Adjust the audio levels to ensure clear communication.

6. Test the Connection:

   • Once configured, test the link by transmitting from a radio and checking if the signal is received on the other. Adjusting the squelch levels so only to open when you transmit.
     
   • Pres the nr 1 key on the Microphone to enable the TX and then press the # key on radio mic to disable TX and enable RX
     
   • Make adjustments on pot to adjust the TX modulation if necessary to improve audio quality and signal reliability.

7. Secure the Connection:

   • Enable any available security features such as encryption or password protection to secure the communication link.
   • Regularly update the firmware of the ROIP-102 devices to maintain security and performance.

8. Monitor and Maintain the Link:

   • Use the web interface to monitor the status and performance of the link.
   • Perform regular maintenance and troubleshooting as needed to ensure continuous operation.

Additional Considerations:

• Ensure that both locations have stable internet connections to prevent interruptions in communication.
• If you experience issues with connectivity, check firewall settings, and ensure that the necessary ports are open for communication.
• Consult the ROIP-102 user manual and support resources for specific configuration details and troubleshooting steps.

By following these steps, you should be able to link two ROIP-102 devices to radios over the internet effectively.

 

Point to Multi point repeaters using Asterisk server.

To set up an ROIP-102 device with Asterisk, follow these steps:

Prerequisites:

1. ROIP-102 device(s)
2. Asterisk server
3. Network infrastructure with stable internet access

Step-by-Step Guide:

1. Configure ROIP-102 Device:

• Connect ROIP-102 Device:

  • Connect the ROIP-102 to the radio and power it on.
  • Connect the ROIP-102 to your network using an Ethernet cable.

• Access ROIP-102 Web Interface:

  • Find the device's IP address using a network scanning tool or check the DHCP client list on your router.
  • Enter the IP address in a web browser to access the ROIP-102 web interface.
  • Log in with the default credentials (refer to the manual).

• Network Settings:

  • Assign a static IP address to the ROIP-102 to ensure consistent connectivity.

• SIP Settings on ROIP-102:

  • Navigate to the SIP settings section in the web interface.
  • Enter the following details:
    • SIP Server: IP address or hostname of your Asterisk server.
    • SIP Port: Default is 5060.
    • SIP User ID: A unique identifier for the ROIP-102 device.
    • Authentication ID: Same as the SIP User ID.
    • Password: A strong password.
  • Save the settings and reboot the ROIP-102 if necessary.

2. Configure Asterisk Server:

• Install Asterisk:

  • Ensure Asterisk is installed and running on your server. Installation steps vary by operating system.

• Configure SIP in Asterisk:

  • Edit the sip.conf file to add a new SIP peer for the ROIP-102 device:

  [roip102]
  type=friend
  host=dynamic
  secret=your_password
  context=default
  disallow=all
  allow=ulaw
  allow=alaw
  dtmfmode=rfc2833
  qualify=yes
   

•     Replace your_password with the password set in the ROIP-102 SIP
       settings.

   Configure Dialplan in Asterisk: 

•     Edit the extensions.conf file to add a dial plan for the ROIP-102 device:

[default]
exten => 1001,1,Dial(SIP/roip102)
exten => 1001,2,Hangup()

This example assigns extension 1001 to the ROIP-102 device. Adjust as needed.

3. Test the Setup:

• Register the ROIP-102 with Asterisk:

  • Check the registration status on both the ROIP-102 web interface and the Asterisk CLI (asterisk -rvvv).
  • Then run reload command to load the new config
    
  • Use the command sip show peers in the Asterisk CLI to verify that the ROIP-102 device is registered.

• Make Test Calls:

  • Use a softphone or another SIP device to dial the extension assigned to the ROIP-102.
  • Verify that the call is routed correctly and that the radio communication works as expected.

4. Secure the Connection:

• Firewall and Security Settings:

  • Ensure that only necessary ports (e.g., 5060 for SIP) are open on your firewall.
  • Use strong passwords for SIP authentication.
  • Consider using fail2ban or a similar tool to protect against brute force attacks.
