The HP Poly Edge E400 with Power Supply brings the same strong mid-range feature set as the standard E400, with the added flexibility of a bundled power adapter for locations where PoE is not available. Eight SIP lines give it solid multi-line capacity, and built-in Bluetooth enables wireless headset pairing without additional hardware. HD Voice keeps call quality clear and natural throughout the day, and the 2.7-inch color display makes navigating the phone’s features straightforward. Having both PoE and PSU options in this bundle means the phone can be placed wherever it is needed without concern for the local network infrastructure. Compatible with most SIP-based platforms and provisioned using Poly’s standard tools, the E400 PSU bundle is a practical choice for organizations managing deployments across office and remote locations with varying infrastructure setups.
