Description
The GRP2670 is the most complete model in Grandstream's GRP series. Its 7-inch capacitive touch screen (1024 x 600 pixels) replaces physical keys with 48 virtual multi-purpose keys that can be set up for line monitoring, speed dials or call functions. It registers up to 16 SIP accounts on 12 lines and starts 5-way audio conferences. The full-duplex HD speakerphone and Noise Shield technology keep background noise down. For connectivity, it combines two switched Gigabit ports with built-in PoE, dual-band 2.4 and 5 GHz Wi-Fi, Bluetooth, an RJ9 headset port with Plantronics EHS and a USB port. Centralized management runs through the GDMS platform, and security relies on secure boot, dual firmware images and encrypted data storage.

Use and tips
The GRP2670 is meant for desks that monitor many lines: executive assistant, switchboard, reception of a practice or of an SMB with several dozen extensions. The 48 virtual keys remove the need for an expansion module, and Wi-Fi lets you install it where no network socket is available. On a PoE switch, the supplied power adapter stays in the drawer. To fix the phone to a wall, plan the GRP_WM_L kit. If the touch screen is not essential, the other models in the GRP series offer simpler configurations with physical keys.
