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 cal ls 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 setti ngs. E ach
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.
