Product Description

The 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 TAA compliant IP phone on the GSA schedule, it meets federal sourcing requirements while retaining the full Edge E feature set. 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 government offices. Power over Ethernet (IEEE 802.3af/at) simplifies installation and 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. Browse related Poly voice and desk phone hardware to complete the deployment.
