New features and improvements in this release

Pexip Infinity deployments have the ability to burst into the Amazon Web Services (AWS) cloud when primary conferencing capabilities are reaching their capacity limits, thus providing additional temporary Conferencing Node resources.

This provides the ability to dynamically expand conferencing capacity whenever scheduled or unplanned usage requires it. The AWS cloud Conferencing Nodes instances are only started up when required and are automatically stopped again when capacity demand normalizes, ensuring that AWS costs are minimized.

Video watermarking overlays a small transparent image onto the main speaker video during a conference. This enables you to add your own imagery, logos or information to the video stream.

Video watermarking is enabled by default, and applies a Pexip logo to all conferences (VMRs and Virtual Auditoriums) running on new installations and on upgrades of existing installations. Watermarks are not added to calls placed via the Pexip Distributed Gateway.

The watermark image can be disabled or customized via the theme applied to the conference, allowing you to have a different watermark per VMR, if required.

The external policy API has been enhanced to include:

• New directory information request to obtain a list of phonebook aliases. The directory information can be used by Infinity Connect desktop clients and Infinity Connect Mobile clients that are registered to a Pexip Infinity Conferencing Node.
• New registration alias request to enquire if an alias is allowed to register to a Pexip Infinity Conferencing Node.
• Ability to administratively enable or disable support for individual API request types.

Pexip Infinity's call licensing model can support audio-only call licenses, port (video call) licenses, or a combination of the two.

On upgrade to version 13, all existing call licenses are treated as port (video call) licenses.

New alarms have been added on the Management Node for when nodes are not correctly synchronized for NTP, and when there are connectivity or configuration synchronization issues between nodes.

The alarm icon displayed on the Pexip Infinity Administrator interface is now a red triangle.

Significantly improved media transport robustness for Chrome-based WebRTC clients (Infinity Connect desktop client and Infinity Connect Web App on Chrome browsers).

Negative acknowledgements and RTP retransmission have been implemented for video sent between Chrome-based clients and Pexip Infinity.

The following administrative usability improvements have been made:

• You can use the Pexip Infinity Administrator interface to transfer a participant to another conference.
• Improved conference media graph — when viewing the status of an ongoing conference the media graph now highlights the nodes and endpoints within each system location. You can also view the current media load for each Conferencing Node, see real-time packet loss data for each connection, and use your mouse to pan and zoom the graph.
• You can view the current and historical (last 7 days) capacity and media load of a system location.
• You can view the historical (last 7 days) media load of a Conferencing Node.
• The Pexip Infinity Administrator interface now uses drop-down menus and has a lighter color scheme. (The submenu groupings and order are unchanged.)
• Tables now allow multi-level sorting.
• The status of a self-signed TLS certificate on the Management Node or on a Conferencing Node is shown as Temporary.
• You can specify a free-format description when configuring NTP, DNS and syslog servers.
