What's new in version 32?

Pexip's Cloud Video Interop (CVI) integration with Microsoft Teams has been enhanced:

• New layout features:

  • The Teams-like layout now supports multiscreen participant display and receiving the presentation stream as part of the layout mix. Note that this layout is still a technology preview feature, and is only recommended for use with Teams gateway calls.
  • Support for Microsoft's Large Gallery view: you can introduce a DTMF conference control command ("toggle_teams_large_gallery") into your themes that allows VTC participants to toggle between their current layout and Microsoft's Large Gallery view. Toggling to Large Gallery view is a technology preview feature in this release.

• Changes to the installation/upgrade scripts are:

  • Microsoft Graph PowerShell is now used for creating the Teams Connector API app and for deploying the Teams Connector.
  • You must be using Az module version 9.0.1 or later (previously it required 7.0.0 - 8.3.0).
  • The strong API app password generation is now performed by Azure AD.

  Note that when upgrading to version 32 you can continue to use your existing Teams Connector API app that you have previously deployed.

• Other administrative changes are:

  • The v32 Pexip Teams Connector uses the latest Microsoft Teams SDK for interoperability. This latest SDK addresses issues with the previous SDKs and also provides new features which will be used in future releases of the Teams Connector. However, there is a change in call capacity meaning that each Teams Connector instance can now handle approximately 10 calls (previously 15), although the exact capacity of each instance can vary depending on various factors such as call resolution, the number of presentation streams, and the number of participants in the Teams meetings. Microsoft are currently working on increasing the call capacity for a future release of their SDK.

    Users of scheduled scaling should review the number of instances that they need to add, and then adjust their scaling policies as appropriate.

  • The destination port ranges from Microsoft Teams (O365) to the Teams Connector load balancer are now 11000-11399 and 12000-12399 (previously they were 10000-10399 and 11000-11399). Note that these changes do not affect the Teams Connector Network Security Group (NSG) rules as they operate behind the load balancer.
  • Azure Storage key rotation is no longer performed as shared key authentication is now disabled. In addition, Teams Connector VMs now use managed identities instead of SAS tokens to access storage accounts.

When configuring One-Touch Join meeting processing rules, there is a new Microsoft Teams SIP Guest Join option for the meeting type. This replaces the need to use a custom rule when enabling the "SIP Guest Join" feature for Teams.

Note that the format of invitations to cloud-based or externally-managed meetings can often change. Using the latest versions of Pexip Infinity and the dedicated OTJ meeting types will ensure best future compatibility.

This release contains the following administrative improvements:

• You can now configure a site banner to appear across the top of every webpage of the Pexip Infinity Administrator interface. You can go to Platform > Global settings > Management web interface configuration and define the text to display, and choose the text and background colors.

• The Pexip Infinity Administrator interface now contains a search box (above the menu bar) that lets you search for configuration settings based on their associated menu, field name or field label text.

• When enabling automatic backups, you can now configure the start hour per day and set it to run multiple times per day.

Administrators can now specify, via manual customization, multiple background images for users to select from.

Note that this replaces the bgImageUrl option — for more information, see Changes in functionality below.

TLSv1.3 is now enabled on all services

TLSv1.3 is now enabled on all services by default (and cannot be disabled).

Deployments running in FIPS compliance mode

Pexip Infinity v32 and later running with FIPS cryptography enabled now has FIPS 140-3 compliance and requires RSA private keys that comply with SP800-56b. Any keys generated by earlier Pexip Infinity versions running with FIPS cryptography enabled are already compliant. The upgrade process will endeavor to fix any non-compliant keys installed on the system, but there is a small subset of possible keys that cannot be fixed (the Certificates > TLS Certificates page on the Administrator interface will display a status of "Private key is unusable" for any such key, and those keys will then need to be replaced). Administrators uploading their own keying material must ensure compliance with SP800-56b (any non-compliant keys will be rejected).

The X-Frame-Options setting has been removed from the security wizard. The CSP frame-ancestors directive supersedes the X-Frame-Options setting and the system now calculates the X-Frame-Options value based on the configured CSP (Global Settings > Security > HTTP Content Security Policy Header).

The default CSP for new installations now includes frame-ancestors 'self'.

On upgrade to version 32, frame-ancestors 'self' will be automatically added to the existing CSP unless there is an existing frame-ancestors directive.

When running the installation wizard, if Enable incident reporting is selected, administrators are now required to provide a contact email address. (This address can be changed at any point after installation via Platform > Global settings > Reporting > Contact email address.)

The address will be used by Pexip Support when following up on any incident reports received from your deployment.

Voice Focus (a voice activity feature that distinguishes between actual speech and background noise) has improved accuracy and better performance. When enabled it now uses the equivalent of an extra 4 audio connections per participant (previously an extra 6).

Infinity Connect legacy webapp

The original "legacy" version of the infinity Connect web app, "Webapp1", is no longer actively developed or maintained and has been removed from the default installation of Pexip Infinity.

If you still require access to this version, please contact your Pexip authorized support representative.

Pexip Smart Scale is being deprecated from Pexip Infinity version 32. Customers currently using this feature should contact your Pexip authorized support representative for information about a replacement offering.
