As a PoE desk phone with expansion module support, it deploys over a single network cable and scales with one Poly Edge E Expansion Module. HD voice and Poly noise-reduction technologies keep conversations clear in open offices and shared workspaces.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe Poly Edge E400 anchors the E400 series with a 3.5-inch color display and 8 line keys for professionals who manage steady call traffic. As a business VoIP phone it supports wideband HD voice through G.722 alongside G.711 and G.729AB for interoperability with hosted and on-premises SIP platforms. Poly NoiseBlockAI and Acoustic Fence suppress background and keyboard noise on the transmit path, keeping conversations intelligible in open offices. Power over Ethernet (IEEE 802.3af\/at) removes the need for a separate adapter during rollouts and simplifies desk cabling. It accepts one Poly Edge E Expansion Module when additional line keys are required, so this professional SIP desk phone adapts as roles change. IT teams provision and monitor the fleet through Poly Lens for consistent firmware and configuration across sites. Its compact footprint suits professional offices, reception positions, and shared workstations.
