1 Introduction

AudioCodes’ RXV81 is a standalone Microsoft Teams Rooms on Android™ (MTR) video bar that takes advantage of plug-and-play simplicity to deliver a familiar and exceptionally productive Microsoft Teams meeting experience.

Outstanding image clarity and enhanced voice quality ensure that remote participants can see and hear everyone in the room and can also participate in full Teams video and content sharing sessions.

The RXV81 stands out with its video and audio capabilities, embedded speaker and a 6-element microphone array, as well as Full HD and ePTZ with 5x zoom. These combine seamlessly to make every meeting interactive and personable.

Stylishly designed and quick to set up, the RXV81 is by default a standalone MTR specifically designed for huddle rooms and small shared rooms, as well as for managers’ and executives’ personal offices in today’s busy hybrid workplaces. When used as a standalone MTR, video and sharing are displayed on the TV screen and meetings are controlled via AudioCodes’ RX-PAD Meeting Room Controller or the remote control (RC).

In addition to standalone mode, the RXV81 can be used in ad hoc peripheral mode. In this mode, customers connect the RXV81 to a BYOD (Bring Your Own Device) (PC/laptop) running a UC client; the BYOD displays meeting video and content and meetings are controlled via the BYOD (join, accept, manage participants). Audio/video (camera ePTZ, mic mute) can be controlled via the UC client or the RC (camera on / off, mute, volume).

Deployment is straightforward with its robust mounting element and minimal cable connections. The RXV81 is supported by AudioCodes’ Device Manager, a plugin of the AudioCodes One Voice

Operations Center (OVOC), allowing IT managers to remotely oversee and upgrade all deployed devices with ease from anywhere.

User's & Administrator's Manual 1. Introduction

1.6 Security Guidelines

The RXV81 is an AudioCodes Native Teams Android-based device purpose-built and customized for Teams calling and meeting and designed to enhance security as part of the default use.

Though customers might see Android-based systems as prone to security issues, security is much less a concern on devices that are purpose-built for Teams meeting and calling.

When analyzing the security of the device there are two levels that should be addressed:

 Authentication and security with regards to Teams connectivity and use  Android level / system of the device

1.6.1 Microsoft Teams Security Guidelines

 Following are AudioCodes’ recommendations with regards to device security:

• Use “sign-in with other device option” – using this mode the user does not type the

password on the device, instead obtains a code to be used to sign-in on his PC/laptop; the device obtains a private token that enables it to access Teams cloud; this token, unlike a password, allows only that device which obtained it to reuse it. The token is stored on the secured file system.

• Leverage Multi-Factor-authentication (MFA) to improve the security of the sign in.

• IT can consider reducing the expiration time of the sign in for devices which are

connected remotely (outside the organization network) vs devices in the organization premise.

 Visit Microsoft technical pages and learn more on security guidelines and policies for

Microsoft Teams adoption:

• Overview of security and compliance - Microsoft Teams | Microsoft Docs

• Identity models and authentication for Microsoft Teams - Microsoft Teams | Microsoft

Docs

• Sign in to Microsoft Teams - Microsoft Teams | Microsoft Docs

1.6.2 Android Level Security Hardening

This section describes the major changes performed on the system/Android level that were incorporated into the device to improve its security.

Google Play Services

Goggle Play services were removed from the device software – no access is allowed to any Google store or Play services.

 The device update of the Android software and application is done via special software

components that either connect into Teams Admin Center or to AudioCodes Device Manager over secured channel.

Running Android in Kiosk Mode

Android Kiosk Lockdown software is the software that locks down the Android devices to just allow the essential apps by disabling access to the Home/Launcher. Using Android Kiosk Lockdown software, the Android devices can be converted into public kiosk terminals or secured work devices.

 Only specific Microsoft apps and AudioCodes signed apps that were certified and approved

in the certification process can run under the Kiosk mode; even if a malicious user managed to install a new un-authorized app on the file system – the launcher on the device will only run those specific approved apps and this cannot be changed in run time (only with new software code that is provided by AudioCodes).

Version 2.2 13 RXV81 MTR on Android Video Collaboration Bar

Page 14

RXV81 MTR on Android Video Collaboration Bar

Screen Lock

AudioCodes Native Teams devices use a screen lock mechanism to prevent any malicious user/users from gaining access to Calendar information and / or Active Directory list of employees and / or triggering unauthorized Teams calls from the device. After enabling screen lock, the device automatically locks after a preconfigured period; a code is required to unlock the device and resume full operation.

AudioCodes Private Key

The system software on the device is signed with AudioCodes private key – users can replace the complete software only with new software that is also signed by the AudioCodes private key. This prevents the user from replacing the complete OTA package of the device with any new system software unless this software has been fully signed by AudioCodes.

Android Debug Bridge (ADB)

AudioCodes disables the Android Debug Bridge (ADB) application and keeps the Teams app running in the front all the time, which means there is no way to install other Apps from unknown sources and sideloading.

App Signing

Android requires that all apps are digitally-signed with a developer key before installation; currently the device verifies that the apps are signed by Microsoft. App signing prevents malicious user/users from replacing a Microsoft-signed app with an app that "pretends" to be Microsoft but which lacks the private key that is known only to Microsoft.

Web Browser

The device does not include a Web browser – users cannot browse to the public internet or internal intranet– all Web services are customized to connect to O365 services and AudioCodes managed services such as One Voice Operations Center (OVOC).

Without a web browser, malicious user/users will not be able to access the device and browse from it as a trusted device into the customer network.

Remote Configuration Management

The Native Teams device does not have an embedded WEB server – configuration and management is performed using one of the following remote interfaces:

 Microsoft Teams Admin Center (for Native Teams devices) over HTTPS protocols – this is

enabled after successful sign-in authentication process.

 AudioCodes Device Manager (part of AudioCodes OVOC suite) over HTTPS.  Debugging interface over SSH. Note that SSH MUST be disabled by default and enabled

only per specific case for debugging-purposes only.

AudioCodes Device Manager Validation

The IP phone validates the AudioCodes Device Manager identity using known root CA:

 The device is shipped with known Root CAs installed. See AudioCodes Root CA Certificate.

 For the initial connection phase, the AudioCodes Device Manager should access the device

using a known CA.

 Once a successful secured connection has been established between the device and the

Device Manager, the user can replace the root CA on the Device Manager and on the phone and re-establish the connection leveraging any private root CA.

User's & Administrator's Manual 14 Document #: LTRT-18256

Page 15

User's & Administrator's Manual 1. Introduction

Sandboxing

AudioCodes Native Teams devices use Android Application Sandbox so that each application can access its own data and is isolated from other applications. This prevents a malicious app from accessing the code or the data of other applications in the system.

Keystore

With AudioCodes Native Teams devices, the certificate keys are encrypted on the device file system.

Device Certificate

AudioCodes Native Teams devices are shipped with a unique certificate which is signed by AudioCodes Root CA.

Data Protection

AudioCodes Native Teams devices run Android which has integral procedures for protecting and securing user data.

Device File System

The device file system is encrypted on the RXV81 device – customers may enforce a policy of device encryption via Microsoft Intune.

Debugging Interface

 The device leverages SSH as a debugging interface.  AudioCodes recommends that customers disable SSH on the device – this can be done via

the AudioCodes Device Manager (OVOC).

 AudioCodes recommends changing the Admin password from the default, which can be

done via Teams Admin Center or AudioCodes Device Manager (OVOC).

 When debugging of a specific device is required, the user can enable SSH on specific

device/s, access SSH with the new Admin password for debugging phase and disable SSH once debugging has been completed.

1.6.3 Android Security Updates

In addition to all the above, AudioCodes regularly adopts and integrates the Android security updates. For reference see https://source.android.com/security/bulletin/2019-10-01

1.7 Certificate Enrollment using SCEP

The device supports certificate enrollment using Simple Certificate Enrollment Protocol (SCEP) using Microsoft’s Network Device Enrollment Service (NDES) server without using AudioCodes' OVOC, thereby allowing device certificates and CA certificate provisioning to be scaled to multiple devices.

After devices are provisioned with a SCEP-related configuration, they receive a CA certificate from the NDES (via parameter ‘security/ca_certificate/0/uri’), issue a Certificate Signing Request (CSR) to the NDES and receive a device certificate signed by the CA certificate (the one that the device received from NDES).

Network administrators must configure the following three parameters:

 security/SCEPEnroll/ca_fingerprint

 security/SCEPEnroll/password_challenge  security/SCEPServerURL

The next table shows the parameter descriptions.

Table 1-3: SCEP Parameters

Parameter Description

security/SCEPEnroll/ca_fingerprint Define the thumbprint (hash value) for the CA

certificate. Default value: NULL. Network admins must set its value to (for

example):

3EBE50003ABF1DF5E6B5A3230B02B856

security/SCEPEnroll/password_challenge Define the enrollment challenge password.

value: NULL. Network admins must set its value to (for

example):

7A7F9FC4BB7625F0935E67EA6D6322ED

security/SCEPServerURL Define the NDES server’s URL. Default: NULL.

Network admins must set its value to (for example):

https://ndes_derver

security/SCEPEnroll/renewal/advancethreshold Define the renewal advance threshold of the

device certificate. Configure between 50 and 100 (in units of

percentage) Default: 80 This indicates that a renewal of the certificate

Figure 3-2: RXV81 Camera Settings

Note:

• During a call, all users who are signed into the RXV81 – Admins and personal users -

can change Camera settings, including the presets. All have the permissions required to do so. When the call ends, the RXV81 reverts to its preconfigured presets.

• Using a Teams shared account, only the Admin can access Camera Settings in idle

and edit camera presets; the user can only move between the defined presets during a video call/meeting. The user can change Camera Settings during the meeting but the changes are not saved.

• Changing camera settings during a meeting can be done without turning off the video

to remote parties.

• The option to access Camera settings from the RXV81’s Device Settings still exists;

administrator permissions will be required in this case.

• The Camera settings option allows saving different camera settings to be used in a

video call so that users can switch easily between predefined camera settings (camera presets) per user requirements in the call.

Note: Users can toggle between the presets, a convenient way to move from one preset

to another, to view each preset and to reconfigure a preset. Click the Camera Views option and in the Select View menu that opens, choose the required preset.

♦ Allows you to configure ‘VLAN Interval’.

'VLAN interval' refers to CDP/LLDP advertisements' periodic interval. Default: 30 seconds. You can increase or decrease the intervals between the CDP/LLDP packets that are sent, based on network traffic and topology.

Note:

• In versions before 1.19, if network VLAN mode ‘/network/lan/vlan/mode’ was set to LLDP,

the device retrieved the VLAN and LLDP switch information (for location purposes) from LLDP.

• From version 1.19, LLDP switch information (for location purposes) is retrieved when

parameter network/lan/lldp/enabled=1 (even when VLAN is retrieved from CDP or VLAN is disabled or VLAN is Manual).

4.1.10 Configuring DSCP for QoS

The RXV81 Teams application supports DS (Differentiated Services) containing a differentiated Services Code Point (DSCP) value and an ECN (Explicit Congestion Notification) value, for monitoring Quality of Service (QoS).

DSCP is part of the IP header that defines the type of routing service to tag outgoing voice packets originated from the device. It informs routers that this packet must receive a specific QoS. Values can be set in decimal (e.g., 184) or hexadecimal (e.g., 0xb8). The default value is 0xb8 (184).

The DSCP value for audio is 0x46. The DSCP value for video is 0x34 (screen sharing is not supported). See also Microsoft's website

Note: The DSCP value can be adjusted on the server; it cannot be adjusted on the client.

for more information.

The figure below shows the recommended port ranges.
