### **Firmware version 2.49.0 for AXIS Network Answering Units includes the following changes**

#### **Precautions to be taken during update to FW version 2.49.x**

* Empty device names are no longer supported. Set the name via Services > Web Server > Device Name. If left blank, the device may fail to update.
* Devices can no longer be downgraded below version 2.47.0 after updating.
* Devices no longer accept certificates signed with 1024-bit RSA keys. These certificates are removed during the update and must be replaced with certificates using at least 2048-bit RSA or ECC keys. Services relying on weaker certificates will stop functioning, and a warning will appear next to the certificate selection parameter in the web interface.
* In EAP-TLS mode, 802.1x no longer supports RADIUS certificates containing the `id-kp-clientAuth` Extended Key Usage. If such certificates are used, they will be rejected after the update, resulting in the device being unable to authenticate and connect to the network.

#### **New Functions and Improvements**

* AXIS I5304 now includes an optional Control Center screen, providing access to additional HTTP commands and widgets such as date and time. It can be enabled and customized under Services > Control Center. This feature allows you to define which screen appears when the device wakes—either the classic home screen or the customizable Control Center. The second screen remains accessible with a simple swipe.
  * A background image that is common to both the Home Screen and Control Center can be uploaded via Hardware > Display > Background Image.
* Native integration with Microsoft Teams has been added, allowing bidirectional calling with our devices and enabling door unlocking directly from the Teams client. Configuration is available via Services > Integration > MS Teams.

#### **Essential Corrections**

* Updated several internal libraries.
* Increased stability of AXIS I5304 during repeated calls.
* Syslog now correctly logs initial packets after reboot.
* Improved overall SIP performance and stability.
* Important bug fixes.
