Customers might perceive Android-based products as vulnerable to security issues but security is less of an issue on devices purpose-built and cus- tomized for Microsoft Teams calling and meeting. Security is in fact enhanced on these devices as part of their default use . When analyzing device security, two levels must be addressed: ■ Authentication and security with respect to Teams connectivity and use ■ Android level / system of the device AudioCodes recommends the following: ■...

intranet. All Web services are customized to connect to Office 365 services and AudioCodes' managed services such as the One Voice Operations Center (OVOC). Remote Configuration Management Native Teams devices do not have an embedded Web server. Configuration and management are performed using one of the following remote interfaces: ■ Microsoft Teams Admin Center (for Native Teams devices) over HTTPS protocols, enabled after a 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 phones validate the AudioCodes Device Manager identity using a known Root CA: ■ The device is shipped with known Root CAs installed. See AudioCodes Root CA Certificate on the next page . ■ For the initial connection, the AudioCodes Device Manager accesses devices 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. - 6 -...
Customers may enforce a policy of device encryption via Microsoft's cloud-based Intune service. Debugging Interface ■ The devices leverage SSH as a debugging interface. ■ AudioCodes recommends that customers disable SSH on devices via AudioCodes' Device Manager (OVOC). ■ AudioCodes recommends changing the Admin password from the default, via the Teams Admin Center or AudioCodes' Device Manager (OVOC). ■ When a device - or multiple devices - needs to be debugged, users can enable SSH on it / them, access SSH with the new Admin password for the debugging phase, and disable SSH once debugging is finished. Android Security Updates AudioCodes regularly adopts and integrates Android security updates. For reference, see https://source.android.com/security/bulletin/2019-10-01 AudioCodes Root CA Certificate The following figure shows the AudioCodes Root CA Certificate. - 7 -...

➢ To mount the phone on a wall: Attach the stand of the phone for the purpose of a wall mounting: Detach the base. Attach it again as you did for a desktop mounting (see Desktop Mounting on the previous page ) only now make sure that it's flatly aligned to lie flush against the wall, i.e., slide the inner rails of the phone stand onto the phone base's inner notches. Connect the AC power adapter, LAN and PC/laptop cords. In the wall, drill two horizontal holes at a distance of 4 7/8 inches (123.8 mm) from one another, in line with the template. Insert two masonry anchors into the holes if necessary. Thread two screws (not supplied) into the two masonary anchors; ensure that the heads extend sufficiently (about 3/16 inch or 5 mm from the wall) for the phone stand's keyhole slots to hang on. Hang the phone stand's keyhole slots on these screws. Before Using AudioCodes Devices AudioCodes recommends frequently cleaning devices' touch screens especially the screens on devices in common use areas such as conference rooms and lobbies. ➢ To clean a device's touch screen: Disconnect all cables. Spray onto a clean, dry, microfiber duster a medicinal isopropyl alcohol and water solution of 70:30. Don't oversaturate the duster. If it's wet, squeeze it out. - 16 -...

CHAPTER 4 Teams Application C448HD and C450HD | Users & Administrator's Manual In most regions, Daylight Saving Time changes the regional time twice a year. DST Validation allows maintaining accurate time. Two options for phones to get the correct time are: ■ [Recommended] I f the DHCP server offers Timezone Options (100/101), the phone will set the obtained time zone and display the correct time on the screen; the time will be calculated based on an embedded Time Zone database, factoring in DST. ■ If the DHCP server offers Time Offset Option only (2), the phone will assign the obtained time offset to the first matched region in the list but there is a good chance it won’t reflect the actual geographical location, therefore the displayed time might be incorrect in some cases. For example, if the given time offset is GMT-5 and the phone is located in Mexico, the phone will get the time (and the DST setting) from central time and not from Mexico because in GMT-5 there is also Central Daylight Time. The network administrator must make sure the phone can access the following URLs (to check connectivity with the internet): https://www.google.com/generate_204 http://connectivitycheck.gstatic.com/generate_204 http://www.google.com/gen_204 If the internet connectivity check fails, a ‘No Internet Access’ warning pops up on the phone screen.

CHAPTER 4 Teams Application C448HD and C450HD | Users & Administrator's Manual Remote Provisioning and Sign-in from Teams Admin Center Network administrators can remotely provision and sign in to a Teams device. To provision a device remotely, the admin needs to upload the MAC IDs of the devices being p rovisioned and create a verification code. The entire process can be completed r emotely from the Teams admin center. ➢ Step 1: Add a device MAC address Provision the device by imprinting a MAC address on it.
Page 49
CHAPTER 4 Teams Application C448HD and C450HD | Users & Administrator's Manual From the Awaiting Activation tab, select an existing MAC ID. A password is created for the MAC address and is shown in the Verification Code column. You'll need to provide the list of MAC IDs and verification codes to the field technicians. You can export the detail directly in a file and share the file with the technician who is doing the actual installation work. ➢ Step 3: Provisioning on the device Once the device is powered up and connected to the network, the technician provisions the device by choosing the ‘Settings’ gear on the top right of the new ‘Sign in’ page and selecting Provision phone . The technician is then expected to enter the device-specific Verification code that was provided in the Teams admin center on the phone’s user interface. Once the device is provisioned successfully, the tenant name will be available on the sign in page.
