If you have multiple Grandstream devices at your location, please follow these instructions.
*** Note ***
- You will need a router or switch for this to function properly.
First, Do not connect the Devices to the router. Instead, connect a computer to the LAN port of the first Grandstream and power on the Grandstream.
*** Important Note ***
- Do not connect anything into the WAN port of either device at this time. We will get to that point shorty.
- Once you have the computer connected to the LAN port of the first Grandstream, open your browser window and go to http://192.168.2.1 and log into the device with password 123.
- Click on Basic Settings.
- Change the Web Port from 80 to 4200.

While the first Grandstream is rebooting, connect the same computer to the LAN port of the second Grandstream and power on the Grandstream. Open your browser window and go to http://192.168.2.1 and log into the device with password 123.
