Panasonic KX-NT553 KX-NT5xx Series SIP Handset Image 1

Panasonic KX-NT553 executive IP phone with large display and enhanced functionality.

The Panasonic KX-NT553 is an executive-class IP telephone designed for business environments requiring advanced communication features. This mid-to-high tier handset features a large backlit LCD display, 24 programmable function keys with LED indicators, and full-duplex speakerphone capability for hands-free communication.

The KX-NT553 is designed for deployment with Panasonic’s KX-TDE and KX-NCP series IP-PBX systems, as well as the newer KX-NS series unified communications platforms. It supports Power over Ethernet (PoE) for simplified installation and includes a built-in Gigabit Ethernet switch with dual network ports for PC pass-through connectivity.

This handset has been a core component of Panasonic’s business telephony portfolio, though the broader KX-NT5xx series is now considered legacy as Panasonic has shifted focus in the enterprise communications market. The KX-NT553 remains widely deployed and fully functional within existing Panasonic PBX installations.
