HPE J9766C conferencing device

SKU CH-DQGE-MCWRJ MPN J9766C

IP phone optimised for Microsoft Lync with dual RJ-45 ports and PoE support

  • Optimised for Microsoft Lync Unified Communications
  • 3-inch colour display for clear call information
  • Two RJ-45 ports with PoE support
  • Full-duplex speakerphone for hands-free conversations
  • Compact 1.6-inch depth fits any desk

Purpose-built for Microsoft Lync

The HP 4120 IP Phone Series is designed for organisations that standardise on Microsoft Lync Unified Communications and Office 365 collaboration services. It delivers native Lync-optimised features including Better Together mode for integrated voice, video and desktop sharing. Buyers who need SIP interoperability with non-Microsoft platforms or analogue line support will not find those capabilities in this device.

Power and thermal profile

The handset draws power entirely through its PoE-enabled RJ-45 port, eliminating the need for a separate mains adapter and reducing desk cable count. With no internal fan or active cooling assembly, acoustic output is limited to the speakerphone and ringer during calls. The two-port network switch passes through a second Ethernet drop for a PC without additional infrastructure.

Bundled connectivity and setup

Two RJ-45 ports provide uplink and PC pass-through while LLDP-MED advertises voice VLAN and power parameters automatically. A colour display and integrated speakerphone support the full Lync feature set without extra peripherals. No software licences, mounting brackets or analogue adapters are included in the package.

Questions about this item

How do I connect the J9766C to power and the network using the two RJ-45 ports?

Plug the LAN cable into the first RJ-45 port and the PC pass-through into the second; the PoE port draws power automatically so no separate adapter is needed.

Which parts of the 4120 IP phone are most likely to wear out and need replacement?

The colour display backlight, the speakerphone microphone array and the keypad switches are the components that typically degrade after extended daily use.

At what point does the 3.31 lb handset become uncomfortable during long conference calls?

After roughly two hours of continuous hand-held use the weight and 1.6 in depth create noticeable wrist fatigue for most users.
