Software version: PVOS 9.2.0

Release date: June 2025

The build IDs are:

  • CCX Series: 9.2.0.15437

  • Trio C60: 9.2.0.15437

  • Microsoft Teams App Version 1449/1.0.94.2025084203

 

What’s new in PVOS 9.2.0

 

This release of PVOS includes new features, feature enhancements, and important field fixes.

  • Retirement of Poly CCX Microsoft USB Phone mode

    Poly announces the forthcoming retirement of the Microsoft Teams USB Phone mode for Poly CCX Series phones as of the PVOS 9.3.0 release.

  • Zoom shared line appearances, join and merge calls, and participant view

    Shared call appearances on the Zoom service can now interact with point-to-point and conference calls in new ways.

  • SHA256/512 digest authentication schemes for SIP

    RFC 8760 updates RFC 3261 by modifying the Digest Access Authentication scheme used by SIP to add support for additional secure digest algorithms (SHA-256 and SHA-512/256) to replace the older and obsolete MD5 algorithm.

  • SHA256 digest authentication is now available for HTTP based services

    Many HTTP based services offered on Poly CCX and Trio phones now offer SHA256 digest access authentication (RFC 7616). For backwards compatibility with services unable to support SHA256, MD5 remains available, and you can disable it using new configuration parameters to specify which digest algorithm is permitted.

  • Removal of obsolete SSL and TLS protocols

    This release no longer provides compatibility for SSL v2 and v3 and TLS 1.0 abd 1.1 backwards compatibility options. TLS 1.3 is used by default, with a minimum supported TLS version of TLS 1.2 for backwards compatibility.

  • Support for TLS 1.3

    The latest TLS 1.3 standard offers improvements in speed and security of encrypted data. As of this release, TLS 1.3 is always offered when a TLS connection is created, with TLS 1.2 available for far end services that don’t yet support TLS 1.3.

  • Group paging with CCX 350

    CCX 350 now supports group paging. Send and receive broadcast pages with other Poly desk, conference, and wireless phones. When you enable paging and application switching, press and hold the CCX 350 phone's Home button to open the paging menu.

  • Language specific keyboard downloads

    Japanese and Korean keyboards apps will be automatically downloaded and installed from the Poly Lens service when Japanese or Korean languages are chosen from the phone's settings menu. These keyboards will be uninstalled and returned to the default keyboard if the phone's language is changed back to any other language.

  • REST API session management update

    The REST API now offers session based authentication with three new APIs to create, list, and delete session data.

  • Improved troubleshooting for unintended reboots

    Unintended reboots produce core files that can help Poly | HP support staff diagnose software issues. Up to six core files are now listed, and can be deleted or downloaded through the system web interface for admin and advanced user roles.

 

Retirement of Poly CCX Microsoft USB Phone mode

 

Poly announces the forthcoming retirement of the Microsoft Teams USB Phone mode for Poly CCX Series phones as of the PVOS 9.3.0 release.

Poly CCX phones have provided a Microsoft Teams USB Phone base profile that offered limited telephony companion services to a PC's Teams application. After experimentation with this operating mode, Poly has decided to discontinue its support due to limited demand, usage feedback, and ongoing support challenges.

Poly CCX phones continue to offer the full native Microsoft Teams application experience and full support of the Teams app. You may continue to use the phone as a microphone and speaker through a USB cable when in the native Teams app, but advanced call controls aren’t available.

Users of the USB Phone base profile may remain on PVOS 9.2.0 or earlier to use the USB Phone profile, however Poly has no plans to obtain Microsoft USB Peripheral certification for Poly CCX Series phones.

 

Zoom shared line appearances, join and merge calls, and participant view

 

Shared call appearances on the Zoom service can now interact with point-to-point and conference calls in new ways.

  • When another user of a shared line starts a multiparty conference call, the press and hold action on the shared line key now gives you the option to view the conference participants by pressing the Roster softkey.

  • You can join the conference via the Join softkey.

  • If another user is in a point-to-point call, after a press and hold, they can create a three way conference by pressing the Join softkey.

All configuration is managed through the Zoom administrative web portal.

SHA256/512 digest authentication schemes for SIP

 

RFC 8760 updates RFC 3261 by modifying the Digest Access Authentication scheme used by SIP to add support for additional secure digest algorithms (SHA-256 and SHA-512/256) to replace the older and obsolete MD5 algorithm.

 

SHA256 digest authentication is now available for HTTP based services

 

Many HTTP based services offered on Poly CCX and Trio phones now offer SHA256 digest access authentication (RFC 7616). For backwards compatibility with services unable to support SHA256, MD5 remains available, and you can disable it using new configuration parameters to specify which digest algorithm is permitted.

Description

Audio

VOICE-82671

Calls placed on hold experience one-way audio after resuming when SRTP sequence numbers roll over from 65,535 to 0 while the call is held.

Call Management

Call Management

VOICE-82225

Trio

When joining a Zoom meeting protected by a passcode on a Trio C60 running the Zoom Room Controller, the mute LED will change from green to off after several seconds while the "Enter Meeting Passcode" prompt is visible. If the passcode is entered before the LED switches to off, then muting the meeting from the Trio C60's mute button will mute as expected and display a red LED, however, the ZRC app will not reflect the mute state.

Device Management

VOICE-81553

CCX Series

Trio

Scheduled reboots do not work after upgrade to PVOS 9.0.x.

Firmware

Network

VOICE-82781

CCX Series

Trio

CCX and Trio C60 can lose connectivity from the Teams service for extended periods of time in environments where a web proxy PAC file is used that contains helper functions requiring DNS resolution of addresses that are unavailable due to security policy or because they are outside of the local DNS zone of authority and forwarding is not available.

Software

User Interface

VOICE-81527

Poly Trio C60's Web Interface differs from that of the CCX series and is missing the configuration option to allow screen captures without prior on-screen approval from the C60's touch interface.

User Interface

VOICE-83041
