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/GXP1630 will flash the other
available LINE in red. A line is ACTIVE when it is in use and the corresponding LED is red.
