Use and tips
The GRP2612 suits standard workstations that need neither Gigabit nor PoE: individual offices, reception desks, workshops, small branches connected to a regular switch. Each phone registers in GDMS and fetches its configuration on its own, which makes installations of several dozen phones easier. The power adapter is supplied; to fix the phone to a wall, add the GRP_WM_S kit. If your network powers phones over PoE, prefer the GRP2612P; for Wi-Fi, the GRP2612W; for Gigabit, the GRP2612G.
