Handset, Speakerphone and Headset Mode
The GXP2124 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; or switch
between the handset and headset by pressing the headset key. For headsets to operate, the user must plug
the headset to an RJ9 port on the phone, which allows the user to pick-up, speak, or hang-up calls.
Multiple SIP Accounts and Lines
GXP2124 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.
