OVERVIEW OF FUNCTIONS
Grandstream GXP1610/1620/1625/1628 Small-Medium business IP Phone supports the BroadWorks
Shared Call Appearance feature. Incoming calls will appear at multiple locations simultaneously. All
devices where call appearance is shared can be used to answer an incoming call or make a call as if it is
the main user. Calls can be transferred between two phones by simply putting the call on hold at one
phone and picking it up on the other. The Line LED on GXP1610/1620/1625/1628 phone will light up or
flash in different colors, allowing all people sharing the extension to monitor the call status. One important
application for Shared Call Appearance is for an administrative assistant/executive scenario.
