Asterisk 13
Asterisk has been updated to the current Long Term Support version, Asterisk 13. This update provides performance improvements along with support for WebRTC which allows browser calls.
New user experience for Kerio Operator Client
The web based Kerio Operator Client is renamed to Kerio Operator Softphone and comes with a complete design revamp. The softphone is also available as a stand-alone desktop application for Mac, Windows, and Linux. Kerio Operator Softphone supports phone/video calls directly from browsers or the desktop application.
Video calls in the Kerio Operator Softphone
Kerio Operator 2.5 supports video calls directly from browsers or the desktop application.
Kerio Operator Softphone uses the VP8 codec for video calls. Unlike audio streams, video cannot be transcoded in real-time on the Kerio Operator server. Because of that, you can make video calls only to devices/applications that support VP8, for example, to another Kerio Operator Softphone.
MyKerio integration
Kerio Operator 2.5 can be managed remotely via the MyKerio service. The IT administrators who need to manage multiple Kerio devices (Kerio Control or Kerio Operator) can now do it easily in one place. MyKerio can be used for configuration backups and as a relay for sending email notifications. Configuration backup to Samepage is no longer supported.
Shared definitions among devices in the same organization will be supported in the future, as well as the zero-touch MyKerio provisioning for Kerio Operator hardware appliances.
Opus codec
Kerio Operator 2.5 supports the Opus audio codec. Technically, Opus is a merger of SILK (original Skype codec) and Xiph.Org's CELT. Opus can adapt to variable bandwidth - it is able to encode audio to bitrates from 6 bks/s up to 512 ks/s. It works with sampling frequencies from 8 KHz (the standard frequency for codecs like G.711) up to the high-end of 48 kHz. Opus is covered by several patents but the license allows a royalty-free use.
Firebird update
The Firebird configuration database has been updated. The new version of Firebird improves the stability and performance of the system.
New built-in web server
Kerio Operator 2.5 uses Nginx as a new built-in web server. Nginx provides notable performance improvements in the Kerio Operator administration interface and in Kerio Operator Softphone.
Reliable email sending
Kerio Operator 2.5 improves sending of email messages from Kerio Operator, such as notifications and voicemail forwarding. All outbound email messages are handled by an integrated queueing mail server.
Support for Ubiquity phones
Kerio Operator 2.5 comes with auto-provisioning support for Ubiquity UniFi phones.
Support for Htek phones
Kerio Operator 2.5 comes with auto-provisioning support for Htek models UC803P, UC842, UC862, UC924, UC926, Unicorn 3001, Unicorn 3002.
Downgrading from version 2.5.0
If you do a fresh installation of Kerio Operator 2.5.0, you cannot downgrade to previous versions (2.4.x and older). Version 2.5.0 uses a new configuration database format.
Kerio Operator 2.5.0 retains the old database. If you upgrade to Kerio Operator 2.5.0 from an earlier version, you can downgrade back without limitations.
Backups to Samepage
Configuration backups to Samepage have been discontinued. If you were using the backup to Samepage in Operator 2.4.X, please reconfigure your backup to use either FTP or MyKerio.
Saving recorded calls in Samepage is also no longer supported. You can use FTP to save recorded calls outside of the Kerio Operator server.
