Requirements
Identifying Phone Model
To start and successfully complete registration of your Grandstream device you need to know
which phone model to set up.
On the back of each Grandstream phone, there is model information that you should check.
Although various phone models can have exactly the same requirements and installation
procedures, they can also have significantly different requirements and installation procedures,
so that is why it is important to know the model you own which results in you setting up the
device successfully.

To find out the firmware version of your Grandstream device model, open a new browser

interface login screen. Example: http://192.168.1.22.
