Making Phone Calls 
Handset, Speaker and Headset Mode 
The GXP2130/GXP2140/GXP2160/GXP2170/GXP2135 allows users to switch among handset, speaker or 
headset when making calls. Press the Hook Switch to switch to handset; press the Headset button to switch 
to headset; or press the Speaker button    to switch to speaker. 
Multiple SIP Accounts and Lines 
GXP2160/GXP2170  can  support  up  to  6  independent  SIP  accounts;  GXP2140  can  support  up  to  4 
independent SIP accounts; GXP2130 can support up to 3 independent SIP accounts. Each account is 
capable of independent SIP server, user and NAT settings. Each of the line buttons is "virtually" mapped to 
an individual SIP account. In off hook state, select an idle line and the dial tone will be heard.  
 
To make a call, select the line you wish to use. The corresponding LINE LED will light up in green. The user 
can switch lines before dialing any number by pressing the LINE buttons. 
For  example:  If  2  independent  accounts  are  registered  on  GXP2130  /  GXP2140  /  GXP2160  / 
GXP2170/GXP2135, when LINE 1 is pressed, the LINE 1 LED will light up in green. If LINE 2 is pressed, 
the LINE 2 LED will light up in green and the subsequent call will be made through SIP account 2. 
 
Incoming calls to a specific account will attempt to use its corresponding LINE if it is not in use. When the 
"virtually" mapped line is in use, the phone will flash the other available LINE in red. A line is ACTIVE when 
it is in use and the corresponding LED is red.
