What’s New for UC Software 7.2.0

Change to Issue IDs
Starting with UCS 7.2.0, known and resolved issue IDs for Poly phones no longer use the EN prefix. Issue IDs now have the format VOICE-XXXXX. Note that the issue ID numbers also reset when moved to the new prefix category.
If you’re tracking an issue with an ID in the old format (EN-XXXXXX), you can continue to use this number to reference your issue when working with Poly Support.

Features and Updates
This release of UC Software for the Poly Trio solution is for OpenSIP and Zoom Room deployments. It includes all the features of previous releases and important fixes.

Important: Poly doesn’t support Microsoft Teams in this release.

Poly frequently provides software updates with new features and recommends that you regularly update the software on your Poly Trio devices for the best performance and experience.

Important: When you upgrade your Poly Trio system to UC Software version 7.0.3, you can no longer downgrade it to versions earlier than UC Software 5.8.0AA.

Basic Authentication for Web Proxy
Poly Trio phones support basic authentication on web proxy servers. This feature enables you to configure a username and password the phone can use to authenticate with your network’s web proxy server.

Note: At this time, Poly phones don’t support advanced web proxy authentication, such as TLS or certificate authentication.

Set Up a Custom Background on Poly Trio Systems
Replace the phone’s default background image with a custom image or import multiple images that users can select from.

STIR/SHAKEN Call Validation
This release supports the STIR/SHAKEN standard protocol for caller ID verification. The STIR/SHAKEN protocol enables the phone to validate incoming calls to help prevent fraudulent acts such as call spoofing. Depending on the level of validation, the phone displays different icons in the caller ID screen.

Media Security Negotiation
Starting in UC Software 7.2.0, media security is processed separately from RFC 3329.

Turn Off Trio Mics When Using Visual Pro
Visual Pro users now turn the Trio microphones off and use existing external ones. Settings include:

• Auto – All microphones from the Trio, a daisy chained-Trio, or microphones connected to the VisualPro are available for use and the system will dynamically choose which mic is active based on the changing speaking environment.
• TvOnly – The active microphones will be based only on what is available from the VisualPro (Ceiling mics, camera mics, or table top mics). Microphones on the Trio will not be used unless the VisualPro has no other microphone connected to it.
• PhoneOnly – Only the microphones on the Trio or other daisy chained Trios will be used. Any microphone connected to the VisualPro such as camera mics or ceiling mics will never be used.
  For information on how to set these options up, refer to the Trio Administrator Guide.

Poly Experimental Features

Poly sometimes releases experimental features that administrators can enable and evaluate in nonproduction environments.

Note: Experimental features are neither tested nor supported. These features might, or might not, become official features in a future release. For more information about experimental features or to provide feedback on your experience, visit the Poly Community.

Using Multiple Cameras with Trio Visual+
You can connect more than one camera to a Trio system paired with one or more Trio Visual+ accessories. Users can choose which camera to use during a call using the Camera Controls option.
You can also save presets for each connected camera and use the presets to switch between cameras. However, selecting the Home preset option only resets the currently selected camera.

Configure Multi-Camera Support
Set the following parameter values to enable support for multiple cameras with Poly Trio Visual+.

• video.camera.multiCamera.enabled=”1″
• (Optional) mr.pair.maxDevices=<integer equal to 1 + (the number of Trio Visual+ and Trio VisualPro devices paired with the Poly Trio system)>

Switch Between Cameras
You can switch between two or more cameras connected to a Trio system with a paired Trio Visual+ accessory.
You can also save presets for each connected camera and use the presets to switch between cameras. However, selecting the Home preset option only resets the currently selected camera.

1. Do one of the following:
   • During a call, select Camera.
   • Select Menu > **Camera.

** • Select a preset saved for the camera.

Support for Poly Studio USB Video Bar
This release provides experimental support for the Poly Studio USB video bar as a USB camera when connected to a Trio Visual+ accessory paired with a Trio 8500 or Trio 8800 system. However, the Trio system doesn’t use the microphones and speakers of the Poly Studio USB video bar for audio.

Security Updates

Refer to the Poly Security Center for information about known and resolved security vulnerabilities.

UC Software Distributed Files

You can download the software package for Trio systems in ZIP file format and place the package on a provisioning server to provision your devices. Each software package contains configuration files and a sip.ld file for each Trio system.

The sip.ld files are model-specific and are as follows:

• Trio 8300: 3111-66800-001.sip.ld
• Trio 8500: 3111-66700-001.sip.ld
• Trio 8800: 3111-65290-001.sip.ld

If you’re provisioning your phones centrally using configuration files, download the corresponding resource file and extract the configuration files to the provisioning server. Make sure to maintain the folder hierarchy in the ZIP file.

Installing UC Software
You can install UC Software for Trio systems using a provisioning server. You can also install UC Software on Trio 8500 and Trio 8800, using a USB flash drive.
You can configure features for the Trio system using configuration files on a provisioning server, using the system web interface (Web Configuration Utility), or on the phone’s local interface. See the Poly Trio Solution Administrator Guide for more information on configuring features.

Install Trio Visual+ Software for Trio 8500 and Trio 8800
The Trio Visual+ accessory provisions and updates automatically from the Trio 8500 or Trio 8800 it’s paired with–users typically don’t have to interact with the system for manual provisioning and software updates.
The UC Software for the Trio 8500 and Trio 8800 download doesn’t include a dedicated executable file for the Trio Visual+.

Procedure

• Delete the part number from the Trio sip.ld file and do one of the following:
  • Use the renamed sip.ld file to install software for both the Trio system and Trio Visual+ accessory.
  • Copy the Trio file and rename it using the Trio Visual+ part number (3111-66420001.sip.ld).

Installing Trio Visual+ Software for Trio 8300
To use Trio Visual+ with Trio 8300, you MUST provision and update the Trio Visual+ accessory when it’s paired with the Trio 8300 system. You must configure the Trio 8300 and stage the software for the Trio Visual+ using a supported provisioning or boot server.
The standard UC software for Trio 8300 download doesn’t include a dedicated executable file for the Trio Visual+. You can download the separate Trio 8300 software that includes Trio Visual+ from the Poly Online Support Center, then update the Trio 8300 software with the paired Trio Visual+.

You can upgrade the software of the Trio Visual+ accessory when paired with a Trio 8300 system in the following ways:

• Manual update via a USB flash drive.
• Provisioning or boot server via Trio 8300 as a proxy.

Provision and Update Trio Visual+ Paired with Trio 8300 with a USB Flash Drive
You can store configuration files and settings on a USB flash drive and provision or update Trio Visual+ during normal functioning or in recovery mode. Recovery mode enables you to recover the Trio Visual+ to a normal provisioning state when other methods aren’t working or aren’t available.
Trio Visual+ supports only File Allocation Table (FAT) file systems, and Poly recommends using FAT32. If other USB devices are attached to Trio Visual+ system, you must remove them and ensure that the Trio Visual+ system correctly recognizes the USB flash drive you want to install from.
If you use a USB flash drive to provision while a centralized provisioning server is in use, the USB configuration files override server settings. When you remove the USB flash drive, the Trio 8300 system returns to settings you configured on the server. Note, however, that the original server settings are subject to device parameter changes initiated by the USB flash drive. The device parameter changes can alter parameters on the provisioning server and change basic provisioning settings.

Procedure

1. Format a USB flash drive as FAT32. Poly recommends that you use a USB 2.0 flash drive. If you’re using a flash drive that is already formatted, ensure that previous files are deleted from the USB flash drive. The update may fail if the flash drive contains any files other than the update files.

2. Download the latest Trio 8300 software download from the Trio 8300 support page. The file name format is:
   Poly_UCSoftware_Trio8300_with_Visual+_release.zip

3. Extract the ZIP file and move the contents to the USB flash drive’s root folder. The minimum required configuration files are:
   • Primary configuration file: 000000000000.cfg
   • Trio Visual+ sip.ld: 3111-66420-001.sip.ld

4. Insert the USB flash drive into the Trio Visual+, follow the prompt for the Administrator password, and power cycle the device. Allow time for the devices to fully reboot.

Pairing the Trio Visual+ via Trio 8300 Configuration
You can pair a Trio Visual+ accessory to a Trio 8300 system by setting the mr.pair.uid parameter to the MAC address of the Trio Visual+ accessory.
