Release Notes 1. Introduction
Version 1.2.196 7 400HD Series IP Phones for Skype for Business
1 Introduction
This document describes the new features and known constraints of AudioCodes' C448HD and C450HD
IP Phones for Microsoft Teams. The phone’s firmware version is 1.2.196 and the Microsoft Teams
application version is 1.0.94.2020020601.
1.1 Overview
The AudioCodes C450HD and C448HD IP phones are native Microsoft Teams high-end executive
business phones with a large color touch screen and full UC integration for the Native Microsoft Teams
Online market.
The Microsoft Teams C450HD and C448HD are equipped with a 5-inch color capacitive touch screen,
1280 x 720 resolution and optional integrated Wi-Fi and Bluetooth support (C450HD only) (contact your
local AudioCodes representative for more information about regional availability of Wi-Fi / Bluetooth).
The phones can be managed by the Microsoft Teams & Skype for Business Admin Center. For more
information, see https://docs.microsoft.com/en-us/MicrosoftTeams/phones-for-teams.
The C450HD phone also features the option to be used as a Microsoft Skype for Business IP phone,
offered as part of AudioCodes’ Managed IP Phones solution which defines the IP phone as an IT-
managed entity and delivers unique and complete lifecycle management of end-user desktop devices. A
single-click switchover between Microsoft Teams with native client experience and Skype for Business is
supported. The C448HD phone currently doesn’t support this option as it’s for Native Teams only.

Version 1.2.196 10 Document #: LTRT-08459
Enhanced E911
•A new ‘Emergency’ key was added to the phone’s idle lock screen, i.e., to the screen
displayed before the screen that allows entering the PIN code/pattern.
•Users can dial the E911 service from a locked screen without needing to press the
‘Emergency’ key. They only need to dial 911 and then trigger the call from the
speaker/handset or wait for the timeout; they can pick up the handset or press the speaker
button and dial 911 from the lock screen:

Release Notes 2. Version 1.2.196
Version 1.2.196 11 400HD Series IP Phones for Skype for Business
•The ‘Emergency call’ screen with the emergency dialed number is then displayed. Users can
then perform the dialing.
Bluetooth support now provided under Android as a Beta. Handsfree profile where the phone
is able to connect to Bluetooth headset or speaker.
The unlock feature on the C450HD phone for Microsoft Teams has been improved using a
smart PIN unlock mechanism. When users now use the PIN to lock the phone, to unlock they just
need to type the PIN number for the phone to automatically unlock without requiring users to
confirm using the OK button. Moriya
All ‘Settings’ fields that pop up and require the virtual keypad for inputting characters and/or
numbers - such as when the network administrator needs to enter an IP address to debug or when
they need to enter their PIN lock for the security tab - were improved so that the keyboard/keypad
now only takes up half the screen and not the full screen as was the case previously.
