      Grandstream Phone Functions Quick Reference Guide

      Please see the attached quick reference guide regarding phone functions and buttons on Grandstream GXP 21xx IP telephones.

       

      While the button layout / location may differ between phone models, the phone's hard-key functions (buttons with white labels) will not change.

      The soft-keys just beneath the screen pointing to above on-screen functions will change, depending on the mode or state the phone is in.
