MAKING PHONE CALLS
HANDSET, SPEAKER AND HEADSET MODE
The GXP1610/GXP1620/GXP1625 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.
SIP ACCOUNTS AND LINES
GXP1620/GXP1625 can support up to 2 independent SIP accounts; and GXP1610 can support 1 SIP
account. Each account is capable of independent SIP server, user and NAT settings. Each of the LINE
button 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 GXP1620/GXP1625, 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 GXP1610/GXP1620/GXP1625 will flash the other available LINE in
red. A line is ACTIVE when it is in use and the corresponding LED is red.
COMPLETING CALLS
There are several ways to complete a call.
On hook dialing. Enter the number when the phone is on hook and then send out.
