Setup Guide

1. Package Contents

Before you begin, ensure all components are present:

• Grandstream HT818 Gateway Unit
• Universal Power Adapter
• Ethernet Cable
• Quick Installation Guide

2. Physical Connection

1. Connect to Network: Plug one end of the Ethernet cable into the WAN port of the HT818 and the other end into your internet router or modem.
2. Connect Analog Devices: Connect your analog telephones or fax machines to the FXS ports (labeled 1-8) on the HT818 using standard RJ11 phone cables.
3. Power On: Connect the power adapter to the HT818's power port and then plug it into a power outlet. The power LED on the front panel should illuminate.
4. Check Status LEDs: Observe the LEDs on the front panel. The power LED should be solid, and the WAN/LAN LEDs should indicate network activity. FXS port LEDs will light up when a phone is connected and active.

3. Initial Configuration Access

To access the web configuration interface:

1. Ensure your computer is connected to the same local network as the HT818 (either directly to a LAN port on the HT818 if using it as a router, or to your main router if the HT818 is connected to it).
2. Open a web browser (e.g., Chrome, Firefox).
3. Locate the IP address of the HT818. This can often be found via your main router's DHCP client list, or by using a network scanning tool. Alternatively, you can dial *** on a connected analog phone and then dial 02 to hear the IP address.
4. Enter the HT818's IP address into the browser's address bar and press Enter.
5. Log in using the default username "admin" and the password found on the sticker at the bottom of the device.

Note: It is highly recommended to change the default password after initial login for security purposes.

Operating Instructions

Making and Receiving Calls

Once the HT818 is configured with your VoIP service provider, making and receiving calls is similar to using a traditional phone line:

• To Make a Call: Pick up the handset of the analog phone connected to an FXS port. You should hear a dial tone. Dial the desired phone number and wait for the connection.
• To Receive a Call: When your phone rings, pick up the handset to answer the call.
• 3-Way Conferencing: During an active call, press the Flash button (or equivalent on your analog phone), dial the third party's number, and once connected, press Flash again to merge the calls.

Fax Operation (Fax-over-IP)

The HT818 supports Fax-over-IP (T.38 protocol) for reliable fax transmission over your VoIP connection. For optimal performance:

• Ensure your VoIP service provider supports T.38 faxing.
• Connect your fax machine to one of the FXS ports.
• Configure the T.38 settings in the HT818's web interface as per your service provider's recommendations.
• Use a lower baud rate (e.g., 9600 bps) on your fax machine if you experience issues.
