Version 11.3.0 - Release date 18th of September 2017

The 11.3.0 release is major release of the Total Recall VR LinX II technology.

Release 11.3.0 adds additional GenV (5^th generation) technology to the current LinX (4^th generation) Total Recall VR audio logging and call recording technology. The new features in 11.3.0 are:

• Streamlined SIP recording Media Server
• Full support for Cisco BiB recording
• Streamlined RTP recording Media Server
• Active recording of RTP streams from Omnitronics RoIP devices including IPRs and DRGs
• RTSP recording Media Server

Release 11.3.0 introduces enhancements to the SIP recording Media Server that enables a single media server to provide a number of different SIP style recording services. As a result it is now necessary to configure and use SIP trunks to the Total Recall VR that use a specified user name in the SIP “To” header URI in order to identify the desired recording service for each SIP session with the recorder. The following table shows the user names that activate different SIP based recording services:

Cisco BiB recording has been a feature of the LinX (4^th generation) technology for a number of years, however up until this release Total Recall VR created 2 recordings for each SIP call that uses Cisco BiB recording. This is a result of how Cisco BiB operates. Release 11.3.0 adds active VoIP recording channel technology which is capable of  ‘combining’ Cisco BiB calls that relate to a single SIP call into a single recording. As a result, as of this release Total Recall VR creates one recording for each SIP call that uses Cisco BiB recording.

Release 11.3.0 replaces the LinX (4^th generation) RTP recording Media Server with a GenV (5^th generation) media server. As a result, among the many (hidden) benefits, the configuration of the RTP Media Server is now simpler and eliminates the need for separate RTP Streams and RTP Stream Pairs configuration. As of this release, the RTP Stream Pairs configuration is obsolete and users need only configure RTP Streams from now on. However, as a result, users with existing systems that use RTP Stream Pairs for recording RoIP and AoIP streams will have to replace the RTP Stream Pair configuration with equivalent RTP Stream configuration after upgrading to 11.3.0. For example:

The GenV (5^th generation) RTP recording Media Server adds support for recording of RoIP streams from Omnitronics equipment (IPRs and DRGs) in active mode in addition to the passive mode, which remains available. As a result, Total Recall VR recorders no longer need to be collocated with Omnitronics equipment and there is no need to configure SPAN ports on Ethernet switches.

Release 11.3.0 introduces recording of RTP streams via the RTSP 1.0 protocol. The new RTSP recording media server has full support for both interleaved RTP streams (RTP over TCP) and independent RTP streams (RTP over UDP). In addition, clients can send metadata for the session being recorded in the first RECORD message and subsequent SET_PARAMETER messages. The metadata can be in the Total Recall VR proprietary format or the ED-137 format (see ED-137 Interoperability Standard for VoIP ATM Components, Part 3: Recording).

In addition to introducing additional GenV (5^th generation) technology, 11.3.0 introduces the following improvements:

1. The RAID disk management tools allow users to manipulate the bootable state of RAID disks.
2. The Speex transcoder was deprecated as it was consuming considerable resources while it is no longer necessary as disk space is no longer an issue with any of the Total Recall VR models.

Finally, the following defects were removed:

1. Logs are no longer filled with error messages from the analogue DSP cards. Error messages are now logged only once.
2. Recordings on RTP Streams and VRP channels now set the extension fields in the metadata.
