MAKING PHONE CALLS 
HANDSET, SPEAKER AND HEADSET MODE 
 
The GXP2140/GXP2160 allows users to switch among handset, speaker or headset when making calls.

Speaker button    to switch to speaker. 
 
MULTIPLE SIP ACCOUNTS AND LINES 
 
GXP2160 can support up to 6 independent SIP accounts; GXP2140 can support up to 4 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 GXP2140/GXP2160, 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.
