The HP Poly Edge E350 steps up from the E300 with four SIP lines, giving it more capacity for users who regularly handle multiple concurrent calls. The 2.7-inch color display is clean and functional, and the phone’s straightforward layout keeps things simple for users at any level of technical comfort. HD Voice delivers clear, natural audio throughout the day, and the full-duplex speakerphone covers hands-free needs reliably. This bundle includes a power supply unit alongside PoE support, giving it flexible installation options for offices with or without a PoE-capable switch at every desk. The Edge E350 is compatible with most SIP-based platforms and hosted VoIP providers, and it provisions cleanly using Poly’s standard tools. For businesses looking for a reliable, multi-line phone at a practical price point, the E350 is a capable and well-rounded mid-range option in the Edge lineup.
