Key specifications at a glance

Manage everyday calls with ease

Two lines let users handle separate calls without needing a second phone. Dedicated keys support useful tasks such as conferencing, messaging and directory access. Speed dial, caller ID, call waiting, hold and forwarding also help staff manage calls efficiently.

The 3.5-inch backlit display uses clear grayscale graphics. Four context-sensitive soft keys and a two-way navigation button make menus easier to use. Integrated voicemail and an answering machine add practical support for missed calls.

Hear conversations clearly

G.722 wideband audio supports clearer speech through the handset and speakerphone. The built-in speakerphone gives users a hands-free option for suitable calls. Digital volume control makes it easy to adjust listening levels.

Fit it into an Ethernet-based setup

PoE lets the phone receive power over a compatible network connection. Its two Ethernet ports support a tidy desk setup, including a co-located PC. The phone also supports Quality of Service and 802.1x RADIUS security.

Choose desk or wall mounting to suit the workspace. Wall mounting can help in shared areas or where desk space is limited.
