- Vladimir Toncar (Kerio)
Kerio published Kerio Operator 2.5.0 Beta 1 today. This version comes with a large number of technology changes under the hood and with one very visible GUI change - the all-new Kerio Operator Client interface.
Let me summarize the things that are new in Kerio Operator 2.5:
Upgrade to Asterisk 13 LTS
- Plenty of effort went into this change even though it's almost an invisible change for the user. Operator's telephony engine is now Asterisk 13, the latest long term support version. The short-term benefit of this upgrade is the support for the modern Opus codec, and the support for WebRTC (calling from browsers). In the long term, the upgrade guarantees Kerio's ability to develop and maintain Operator as a reliable and safe product.
- Kerio Operator 2.5 can be managed remotely via the MyKerio service.
Kerio Operator Client
- Operator's interface for end users comes with a new design. The Client now includes audio/video phone functionality. To use the Client's phone functionality, either download the native application (available for Mac, Windows, Linux; automatic updates supported on Mac and Windows) or connect to your Operator's web interface with a browser that supports WebRTC (Chrome, Firefox). Naturally, you can use the Client the "old" way as well, to set up your call forwarding, access your voicemail, or work with your desktop phone.
- Note: Kerio Operator Client 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, we recommend that you test video calls between two instances of the Kerio Operator Client. The Operator team is now working on an improvement that will ensure that a video call is only offered when it can be reliably established. This improvement is planned for Beta 2.
- 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.
Reliable email sending
- Version 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 queuing mail server.
Improved web server performance
- Kerio Operator 2.5 uses Nginx as its built-in web server. Nginx provides performance improvements in the Kerio Operator administration interface and in Kerio Operator Client.
Configuration database upgrade
- Kerio Operator uses the Firebird database to keep it's configuration data. The database engine has been upgraded. If you do a fresh installation of Kerio Operator 2.5.0, you cannot downgrade to previous versions. If you upgrade to Kerio Operator 2.5.0 from an earlier version, you can downgrade back without limitations.
Support for Ubiquity phones
- Automatic provisioning for Ubiquity UniFi phones is now available
