Configuring Grandstream GXP21xx Series

Things to do first before you can start the configuration.

• The computer must be connected to the same sub-network as the phone. This can be easily done by connecting the computer to the same hub or switch as the phone connected to. In absence of a hub/switch (or free ports on the hub/switch), please connect the computer directly to the PC port on the back of the phone;

• If the phone is properly connected to a working Internet connection, the IP address of the phone will display in MENU > Status > Network Status. This address has the format: xxx.xxx.xxx.xxx, where xxx stands for a number from 0-255. Users will need this number to access the Web GUI. For example, if the phone has IP address 192.168.40.154, please enter “http://192.168.40.154” in the address bar of the browser;

• There are two default passwords for the login page:
