Enterprise IP phone for high-volume users

The Grandstream GXP2135 is an enterprise-grade VoIP telephone built for workers who manage heavy call traffic. It supports up to eight lines and four SIP accounts on a 2.8 inch colour LCD. Thirty-two digitally programmable BLF and speed-dial keys give quick access to contacts and line status. Integrated Bluetooth pairs with headsets and mobile devices for contact and calendar syncing.

Passive cooling with PoE power

The unit has no moving parts, so it runs silently on a desk or wall mount. Power arrives through the built-in Power over Ethernet interface, removing the need for a separate mains adapter. Dual auto-sensing Gigabit network ports pass data through to a PC without a second cable drop. Typical draw stays within standard PoE limits for the class.

Provisioning options and headset flexibility

Automated setup works through TR-069, XML configuration files or Zero Config with Grandstream UCM series IP PBXs. A USB port adds peripheral connectivity while an RJ9 jack supports EHS-compatible Plantronics headsets. Four-way audio conferencing lets users join multi-party calls directly from the handset or speakerphone. Buyers needing more than four SIP accounts or analogue line ports should consider other models.

Questions about this item

How do I connect the Grandstream GXP2135 to the network and power it, and which port should I use for the PC?

Plug the LAN port into your network switch for Gigabit speed and PoE power; use the second switched port for a PC. The phone auto-senses the link speed on both ports.

Which consumable parts on the GXP2135 will need replacement after heavy daily use?

The handset coiled cord and the RJ9 headset jack see the most wear; replace the cord if audio becomes intermittent and the jack if headset detection fails.

What is the first limit reached when handling back-to-back calls on all 8 lines?

The 32 on-screen BLF/speed-dial keys fill up first, so you lose one-touch visibility for additional monitored extensions during sustained high-volume periods.
