SIP ACCOUNTS AND LINES
GXP1620/GXP1625/GXP1628 can support up to 2 independent SIP accounts; and GXP1610 can support
1 SIP account. Each account is capable of independent SIP servers, 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/GXP1628, 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/GXP1628 will flash the other available
LINE in red. A line is ACTIVE when it is in use and the corresponding LED is red.
