What’s new in PVOS 9.0.0

This release of PVOS 9.0.0 includes the features and important fixes from previous software releases, as well as new features and software updates.

For more information, review the Poly Voice Software 9.0.0 Release Notes.

 

Important update information for PVOS 9.0.0

For all CCX modelsTrio C60 systems this PVOS software release includes a major Android platform update.

Note the following important information before updating to PVOS 9.0.0:

• Don’t turn off the power during the upgrade process.

• After you upgrade your CCX models or Trio C60 systems phone to PVOS 9.0.0, PVOS 9.0.0 becomes the new minimum software version. Returning to PVOS software versions earlier than PVOS 9.0.0 requires the use of a one-time downgrade utility.

• You can upgrade to PVOS 9.0.0 from any earlier PVOS or UC Software version.

• The PVOS 9.0.0 software package contains several upgrade components and is larger than a typical PVOS release. The total duration of the file download, installation, and update can take 30 to 60 minutes or longer, depending on the speed of your network. Most of the upgrade duration is the software download, which occurs as a background service so you can use your phone as normal.

• Your device may restart several times during the upgrade.

  • Upgrading to PVOS 9.0.0 from versions earlier than PVOS 8.1.4 automatically installs PVOS 8.1.4 first, as it contains resources necessary to upgrade the OS to Android 12.

  • Phones already running PVOS 8.1.4 or later skip the interim step and upgrade directly to PVOS 9.0.0.

  NOTE: 

  Your phone doesn’t restart during an active call. If a call is active when the phone completes the download of an installation stage, the restart occurs immediately after the call ends.

• Applicable if upgrading from 8.1.3 or earlier: If a software provisioning server becomes unreachable after the installation of the first component of the software package, the phone remains on the interim software package until the server becomes reachable again. The update attempts to continue after a restart, a check-sync, or at the next scheduled configuration polling time.

 

Android 12 OS upgrade

Upgrade all Poly CCX and Trio C60 models from Android 9 to Android 12 OS to take advantage of security, data privacy, and reliability enhancements from Google.

Applies to products:

• CCX Series

• Trio C60

 

Microsoft USB Phone enhancements

This release provides Microsoft Teams USB phone enhancements for the CCX 350 business media phone.

These enhancements include:

• A new UI with light and dark modes.

• Missed Call, Voicemail, and Meeting Start notifications.

• Single press the Teams button on the phone to bring the PC Teams client to the foreground.

• Single press the Teams button on the phone while a notification displays to enable the context-aware Teams client to open the missed calls and voicemail page or open the meeting lobby.

• Press and hold the Teams button on the phone to raise or lower your hand in a meeting.

• The USB Optimized base profile name in the menus is changed to Microsoft USB Phone.

Applies to products:

• CCX 350

 

Support for ZDM on Trio C60 phones

For Poly Trio C60 phones deployed as Zoom Room Controllers (ZRC), manage ZRC software and firmware upgrades using Zoom Device Management (ZDM) from the Zoom Room section of the Zoom administration portal. In addition, observe basic status and device health information about the Trio C60 operating as a ZRC from the administration portal.

Applies to products:

• Trio C60

 

New REST function: powerStatus

This release adds a new function to the REST API to retrieve the power saving state of the phone.

For more information, review the Poly Voice REST API documentation.

Function:

/api/v1/mgmt/powerStatus

Output:

Success Response:

{ "CurrentState": "<Current LCD
    State>", "Status": "2000" }

Supported values for "<Current LCD State>":

• "PowerOn"
• "PowerIdle"
• "PowerOff"
• "PowerInCall"

Applies to products:

• CCX Series

• Trio C60

 

Limiting call forwarding options

Simplify call forwarding options so that call forwarding is either turned on or off.

Enabling this option removes the menu where the On Busy (CFB) and No Answer (CFNA) call forwarding options are located. Call Forwarding Always (CFA) becomes the sole behavior when call forwarding is enabled on the phone.

To configure this feature, use the following parameter:

feature.forward.bypassTypeSelect

0 (default) - All call forwarding options are available.

1- Call forwarding type selection isn’t available.

Applies to products:

• CCX Series

• Trio C60

 

Configuring SCEP key size

Configure how large a SCEP key is when generated.

Previously the TLS private keys generated locally for SCEP signed certificates were hardcoded to have a length of 2048 bits. The new sec.generated.privateKey.length parameter enables the administrator to configure how large a private key is when generated for SCEP signed certificates.

To configure this feature, use the following parameter:

sec.generated.privateKey.length

2048

3072

4096

NOTE: 

You must choose one of these three value options. Any other value is rejected as invalid by the configuration system.

Applies to products:

• CCX Series

• Trio C60

 

SCEP-sourced credentials available for other TLS profiles

When using the TLS profile management tool located at Settings > Network > TLS > TLS Profiles, the system web interface provides access to Device Platform 3 CA certificates and custom device credentials sourced using SCEP for use in other profiles.

Applies to products:

• CCX Series

• Trio C60

 

Active call preservation after a network interruption

Recover calls after a brief network interruption when either the TCP stream used for SIP messaging is closed by the far end with a TCP FIN or RST or when a TCP keepalive fails to receive a TCP ACK.

After a network interruption, the phone attempts to reconnect through its list of candidate proxies. If the phone restores its registration via the same proxy IP address twas registered to before the failure, the phone sends a re-INVITE for each call active at the time of the interruption to refresh the contact information.

Applies to products:

• CCX Series

• Trio C60

 

Enhancements to outbound caller ID on shared lines

When a shared line is populated across several line keys of the phone, calls that users make from different line keys can now send call control service preferences for unique outbound caller IDs, depending on which line appearance is used.

The caller ID preference follows the tel, sip, and name-addr format, which you can configure to insert in to either the P-Asserted or P-Preferred identity header.

To configure this feature, use the following parameters:

voIpProt.SIP.perLineCallerId.header

PAssertedID (default)

PPrefferredID

reg.X.line.Y.callerID

NOTE: 

X represents the SIP registration index and Y represents the line appearance index.

Use the name-addr format and include escaped characters, such as quotation marks or angle brackets, where appropriate.

Example usage:

voIpProt.SIP.perLineCallerId.header="PAssertedID"
reg.1.line.1.callerid="<sip:+155512345678.service.com>"
reg.1.line.2.callerid="<sip:+12053361XXX@10000191.service.com>"
reg.1.line.3.callerID="<tel:+15551234567>"

Applies to products:

• CCX Series

• Trio C60

 

Minimum TLS default version updates

To adhere to industry security recommendations, Poly desk and conference phone applications use TLS 1.2 as the default version. Starting with PVOS 9.0.0, the backwards compatibility fallback to deprecated TLS versions that was permitted in earlier versions of PVOS on request during TLS negotiation, such as TLS 1.0 or TLS 1.1, is disabled. All TLS communication now uses the TLS 1.2 protocol version.

For services that require deprecated TLS versions, use the following parameters with a value of TLSv1_0 or TLSv1_1 to retain backwards compatibility:

sec.TLS.protocol.sip

sec.TLS.protocol.browser

sec.TLS.protocol.xmpp

sec.TLS.protocol.rtp

sec.TLS.protocol.ldap

sec.TLS.protocol.sopi

sec.TLS.protocol.webserver

sec.TLS.protocol.exchangeServices

This change doesn’t affect software and file provisioning, 802.1x, or syslog, as those default values are set at the time of manufacture and depend on a future manufacturing change. To change the values of factory-applied defaults, use the following parameters:

device.sec.TLS.protocol.syslog.set="1"

device.sec.TLS.protocol.syslog="TLSv1_2"

device.sec.TLS.protocol.dot1x.set="1"

device.sec.TLS.protocol.dot1x="TLSv1_2"

device.sec.TLS.protocol.prov.set="1"

device.sec.TLS.protocol.prov="TLSv1_2"

Applies to products:

• CCX Series

• Trio C60

 

8x8 Work and Dialpad base profiles have been removed

The 8x8 Work and Dialpad base profiles are not available on CCX Series and Trio C60 phones running PVOS 9.0.0.

Support for the 8x8 Work and Dialpad base profiles remains available in previous PVOS releases. Subscribers to these services will receive updates from their provider once the partner application is ready and certified for use on Poly CCX Series and Trio C60 phones running PVOS 9.0.0 or later.

Applies to products:

• CCX Series

• Trio C60

 

Downgrading PVOS 9.X.X to earlier software versions

After you update your CCX modelsTrio C60 systems phone to PVOS 9.X.X, a downgrade to earlier software versions requires the use of a one-time downgrade software package that allows transition from the Android™ 12 OS to the Android 9 OS.

The downgrade package contains two software updates within a single file that are installed in sequence as follows:

• Your phone downloads the downgrade package and restarts to install an interim software version that downgrades the Android OS from Android 12 to Android 9.

• After you install the interim software, your device downloads the second component of the downgrade package and restarts to complete the installation of the PVOS 8.1.5 generally available release.

If you want to use a software version other than PVOS 8.1.5, you can now install that version in the same way that you would install any other PVOS version.

 

Information removed and retained after downgrading

The downgrade process includes a file system format that removes user data and most configurations.

INFORMATION REMOVED WHEN DOWNGRADING

• Microsoft Teams sign-in information

• CCX models

Trio C60 systems

• Poly Studio X Series video bar pairing

Trio C60 systems

• Paired Bluetooth devices

• Configuration changes made or imported from the system web interface that are not listed in the retained information list

• Basic configuration settings such as ring tones, power saving, and OpenSIP speed dials

• SCEP server and client configuration (certificates installed using SCEP are retained)

• Web proxy information

INFORMATION RETAINED WHEN DOWNGRADING

• DHCP, DNS, SNTP, IP, Ethernet, and Wi-Fi settings

• LLDP, CDP, and custom VLAN settings

• Syslog settings

• 802.1x settings, Custom CA certificates, device certificates and keys, and TLS profile settings

Zoom Rooms Controller versions for PVOS 9.0.0

Poly Trio C60 phones optimized for Zoom Rooms act as a controller via the system’s touch user interface and provide audio for Zoom Room meetings through the built-in speakers and microphones.

Limitations

Trio C60 systems operating in the Zoom Rooms PC Base Profile, using PVOS versions earlier than 8.1.1, are signed out when upgrading to PVOS 9.0.0. To retain your sign-in information, you must first update the Trio C60 phone to PVOS 8.1.1 or a later 8.1.x release to enable the Zoom Rooms Controller app to access version 5.15.5. You can then continue to update to PVOS 9.0.0.

Support for ZDM client

Starting with the PVOS 9.0.0 release, Poly is no longer embedding the Zoom Rooms Controller App within our software. We now support the ZDM client and enable the ability to manage firmware and ZRC application updates through the Zoom portal. For more information, visit Support for ZDM on Trio C60 phones.

For the latest setup instructions, review the Integrating Poly Trio Systems with Zoom Rooms Solution Guide.

 

Microsoft Teams versions for PVOS 9.0.0

The Microsoft Teams application is included in each PVOS release for use on CCX 350, CCX 400, CCX 500, CCX 505, CCX 600, and Trio C60 phones. The Teams version included may be updated independently of the PVOS version using the Teams Admin Center.

[AikenMarvin]

One issue so far, getting the "No internet. Emergency calls aren't supported" message on the home screen. HOWEVER, all functions including calling are working. 

[SteffenBaierUK]

Hello @AikenMarvin 

if this is in Microsoft Teams please see the above section stating that PVOS 9.0.0 is not certified for Microsoft Teams.

Please do not use PVOS 9.0.0 with Microsoft Teams.

Best regards

Steffen Baier

[AikenMarvin]

Thank you! Yes I know but I cannot help myself...😬

[SteffenBaierUK]

Hello @AikenMarvin 

I will make it clearer that Microsoft Teams is not a certified platform for the initial PVOS 9.0.0 release

Best regards

Steffen Baier

[Toby777]

We have 15 Trio C60's configured for Zoom Room and for a handful of them, when they are updated to 9.0.0 (from 8.1.6), the device reboots, is pingable for a few seconds on startup and as soon as the Poly logo appears on the device, ethernet stops working and the device is no longer pingable.

For some, a simple power cycle (unplug ethernet PoE and plug back in), fixes the issue but for a few, it doesn't and the device's ethernet connection stops working (device not pingable), and the Zoom Room Controller displays that it's not able to connect.

Only way to fix it would be to enable Wi-Fi and from there, we can access the WebUI and then downgrade it.

Seems like a bug here.

[SteffenBaierUK]

Hello @Toby777 ,

welcome to the HP Poly community.

I suggest you contact our Support organization in your region. Details are in my Signature.
