High Definition “HD” Audio

The KX-UT series of SIP terminals offers ‘best in class’ audio quality, meaning fewer repeated conversations and misheard calls. Offering Wideband High Definition Audio as standard across the range, the KX-NT5xx series offer G.722, G.711, G.726 and G.729a Codecs. Coupled with Enhanced Echo Cancellation and an Expanded Acoustic Chamber, the KX-UT series of SIP terminals offers a superior audio experience to users over handset, speakerphone and optional headsets. The entire range features wideband compliant, hearing aid compatible handsets, and built-in, high quality speaker and microphone.

LCD Displays

Large, clear LCD displays with intuitive User Interface offer fast access to phonebooks and features.

Electric Hook Switch

A built in Electronic Hook Switch (Plantronics compliant) port allows the KX-UT133, KX-UT136, KX-UT248 SIP Terminals to have access to the Plantronics range of DECT enabled headsets. This offers a range of portability and comfort as frequent users are able to move around freely, without being tied down by handsets. The KX-UT248 also supports Bluetooth® headsets.

Paper Label Free (Self-labelling) – Desi-less

8 flexible function keys can be constantly displayed, and up to 24 numbers can be registered. Since the numbers are displayed on the screen, a paper label is not required. (Only KX-UT248)
