when making calls. Press the Hook Switch to switch to handset; press the Headset button to switch to

MULTI PLE SIP ACCOUNTS AND LINES
GXP2120 can support up to 6 independent SIP accounts; GXP2110/GXP2100 can support up to 4
independent SIP accounts; GXP1450 can support up to 2 independent 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 GXP2120/GXP2110/GXP2100/GXP1450, 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.
