Panasonic KX-UT136 KX-UT136X-B User Manual

Voice

Conventional phones have a narrow band voice, which is unable to adequately output low and 
high-pitched sounds. Since the KX-UT series supports the G.722 codec, it can cover a wide range 
including both low frequency and high frequency bands, enabling more comfortable conversations with 
a higher audio quality than conventional phones.

Since the voice of the other party can be clearly heard, 
you can even catch small nuances, for truly comfortable 
conversations.

KX-UT Series  Common Features

The Panasonic KX-UT series SIP phone has received improvement 

upon improvement in order to meet customers' needs.

In contrast to narrow band (G.711) that can only cover part of the human 
voice range, wide band (G.722) covers a wider range of the human voice.

The KX-UT series utilises a speaker box to provide excellent audio quality. 
The KX-UT series incorporates a speaker box in each model to improve 
audio quality at low frequencies (approx. 300 Hz), reduce echoing, and 
reduce sound distortion due to the speaker. The utilisation of a unique 
speaker cone and a magnet more powerful than its predecessors also 
achieves improved audio frequency band sensitivity.

Speaker enhanced characteristics of low frequency 

and high performance

The KX-UT Series saves energy even during standby mode and while calling. By using ECO mode, power 
consumption can be reduced even further.

Easy Configuration

Provisioning provides a system for specifying the initial settings before using a phone without fuss. This 
enables phones to be set up without travelling to customers in remote locations. It is also efficient 
because the settings for many devices can be specified quickly.

Provisioning

When the customer connects a phone to the 
network, initial settings are automatically 
downloaded from the Panasonic Redirect Server. The 
phone is also redirected to a provisioning server by 
the Panasonic Redirect Server.

Easy Initial Settings

Broadsoft DMS (Broadsoft Device 
Management System) is supported.

Broadsoft DMS Supported

Configuration files are sent from the server after being 
encrypted, so that they cannot be easily viewed.

HTTPS is also used for connections between devices and 
the server so that the data cannot be easily viewed.
