Making Phone Calls
Handset, Speaker and Headset Mode
The GXP1760/GXP1780/GXP1782 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
GXP1760 can support up to 3 independent SIP accounts, GXP1780/GXP1782 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.
To toggle between SIP accounts when the line is off-hook, keep pressing the line key until the desired
account show up.
For example: If 2 independent accounts are registered on GXP1760/GXP1780/GXP1782, 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.
