AudioCodes 405HD IP Phone with Power Supply – PoE, Gigabit Ethernet, 2-Line SIP, Teams & Zoom Certified (IP405HDEPSG)

The AudioCodes 405HD with power supply (IP405HDEPSG) is identical to the standard IP405HDEG in every feature — PoE-capable, dual Gigabit Ethernet, 2-line SIP, Microsoft Teams and Zoom Phone certified — with the addition of an included 12VDC power supply adapter in the box. This is the variant to specify when deploying the 405HD in environments where PoE switch ports are unavailable, limited, or reserved for higher-priority devices.

The Telecom Spot Take

Most enterprise deployments run the 405HD on PoE — it's cleaner and more cost-effective. But there are real scenarios where you need the power adapter included: older switch infrastructure without PoE support, conference rooms and common areas where the phone sits near a wall outlet but away from a PoE-capable port, or mixed environments where some desks have PoE and others don't. The IP405HDEPSG ships with the adapter already in the box, so procurement and deployment don't require a separate accessory order for the non-PoE locations. All other capabilities — Teams/Zoom certification, GbE pass-through, USB headset support, auto-provisioning — are identical to the standard IP405HDEG.
