Use and tips
The GRP2612G is aimed at desks that work as a team: assistant, small reception, sales or support department of an SMB, where you need to see who is on the line and transfer without searching. Its BLF keys are programmed from the web interface or GDMS, with no labels to print. Pick it over the GRP2612P when the computer is connected behind the phone on a Gigabit network. On a PoE switch, no power adapter is needed. For wall mounting, plan the GRP_WM_S kit. Without a network socket, the Wi-Fi GRP2612W is the alternative.
