MAKING PHONE CALLS
Handset, Speakerphone and Headset Mode
The GXP21xx allows you to make phone calls via handset, speakerphone, or headset mode. During the
active calls the user can switch between the handset and the speaker by pressing the speaker key. For
headsets to operate, the user must plug the headset to an RJ9 or 2.5mm port on the phone, which allows the
user to pick-up, speak, or hang-up calls.
Multiple SIP Accounts and Lines
GXP2120 can support up to 6 independent SIP accounts; GXP2110/GXP2100 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. The name of each account is
conveniently printed next to its corresponding button. In off-hook state, select an idle line and the name of
the account (as configured in the web interface) is displayed on the LCD and a dial tone is heard.
For example: Configure ACCOUNT 1 and ACCOUNT 2 with Account Name as “VoIP 1”, “VoIP 2”,
respectively and ensure that they are active and registered. When LINE1 is pressed, you will hear a dial tone
and see “VoIP 1” on the LCD display; when LINE2 is pressed, you will hear a dial tone and see “VoIP 2” on
the LCD display.
To make a call, select the line you wish to use. The corresponding LINE LED will light up in green. User can
switch lines before dialing any number by pressing the same LINE button one or more times. If you continue
to press a LINE button, the selected account will circulate among the registered accounts.
For example: when LINE1 is pressed, the LCD displays “VoIP 1”; If LINE1 is pressed twice, the LCD
displays “VoIP 2” 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 GXP21xx will flash the next available LINE (from left to right or from top
