Panasonic KX-NT543 IP Phone with 3-line display and 24 programmable keys.

The Panasonic KX-NT543 is an IP telephone designed for business communications, featuring a 3-line backlit LCD display and 24 flexible programmable function keys. This mid-range IP handset supports Power over Ethernet (PoE) and includes a full-duplex speakerphone, headset port, and Ethernet pass-through for connecting a PC.

The KX-NT543 is part of Panasonic’s NT series of IP phones, designed for use with Panasonic’s business communication platforms including the KX-NS and KX-TDE series PBX systems. It serves as a capable desk phone for office workers who require multiple line appearances and quick access to telephony features.

This model is a legacy product from Panasonic’s now-discontinued business communications division. Despite being discontinued at manufacture, the KX-NT543 remains widely deployed in existing Panasonic PBX installations and is sought after for system expansions and handset replacements.
