Grandstream GS-GXP2135 VoIP phone 8 lines 4 SIP 2.8" 32 BLF

Desk phone for high-volume users

The Grandstream GXP2135 is a desktop VoIP handset built for professionals who handle medium to heavy call volumes each day. It provides eight line keys and four SIP accounts so calls can be managed without constant scrolling. A 2.8 inch colour LCD gives clear visibility of caller details and menus.

Wired build with dual Ethernet and BLF array

The unit connects through two Gigabit Ethernet ports for network and PC passthrough, keeping cabling tidy at the desk. Thirty-two programmable speed-dial and BLF keys sit beside the screen for one-touch access to colleagues and functions. Power is supplied via PoE, removing the need for a separate adaptor.

32 direct-access keys decide fit

The defining specification is the bank of 32 digital speed-dial and BLF keys, which lets a receptionist or team lead monitor and reach many extensions instantly. Buyers who need fewer programmable keys or a smaller footprint should consider other models. Security uses SRTP and TLS encryption, and provisioning supports zero-config with UCM PBXs, XML and TR-069.
