What’s changed in Blueworx Voice Response for AIX Version 6.1?

There are significant enhancements to Blueworx Voice Response for AIX in this release including:

• Support for iLBC compression
  • Blueworx Voice Response for AIX Version 6.1 now supports the iLBC (Internet Low Bitrate Codec, RFC 3951), modes 20 and 30. See Codecs for more information.
• Support for secure SIP
  • Secure SIP provides authentication, as well as integrity and confidentiality of messages, and security for SIP communications on non-secure networks like the internet. Secure SIP can prevent attacks such as tampering with messages, or the impersonation of a user. See Security concepts and Secure SIP for more information.
• Support for secure RTP
  • Secure RTP provides confidentiality and message authentication for RTP data. It can be used to prevent people from listening to or tampering with the audio data sent over a unsecure network like the internet. Blueworx Voice Response for AIX Version 6.1 now supports some optional Secure RTP crypto session parameters (RFC 4568 section 6.3). See RTP Security Negotiation for more information.
• AIX support upgraded to Version 7.1
  • Blueworx Voice Response for AIX Version 6.1 now supports the use of AIX Version 6.1 or Version 7.1 as its operating system.
  • All Blueworx Voice Response AIX device drivers converted to 64-bit operation.

  See AIX support upgraded to Version 7.1 for more information.

• Maximum channel capacity of a machine doubled
  • Using DTNA and VoIP/SIP, the number of Blueworx Voice Response LPARs supported per BladeCenter blade or pSeries has been increased from two to four. An appropriate allocation of CPU, memory, storage and Ethernet resources must be assigned to each Blueworx Voice Response LPAR. As a guideline, a system performance rPerf of 20 can support a 480-channel Blueworx Voice Response LPAR running speech-enabled VoiceXML applications.

    See http://www.ibm.com/systems/power/hardware/notices/rperf.html for further information on rPerf.

    The use of secure SIP and secure RTP, increases the system performance requirements of Blueworx Voice Response by approximately 30%. As a guideline, a system performance rPerf of 26 can support a 480-channel secure SIP and secure RTP Blueworx Voice Response LPAR running speech-enabled VoiceXML applications.

• Improved cache control
  • You can display or expire contents of the Blueworx Voice Response CCXML, VoiceXML, audio file cache.
  • You can select one or all documents or audio files in a cache to expire.
  • You can select documents or audio files older than a specified age or date in a cache to expire.
  • You can now also expire and delete from the disc one or more VoiceXML documents, older than a specified age or date.

  See Improved cache control for more information.

• Enhanced VoiceXML and CCXML application support for call information
  • Support for individual call data session variables for the SIP, ISDN and SS7 protocols.

  See Enhanced VoiceXML and CCXML application support for call information for more information.

• Enhanced CCXML support

  • When using Genesys I-Server, the called number can now be presented in the most appropriate way for TDM or SIP calls.
  • It is now possible to specify that SIP Genesys CTI call transfers are re-routed through Blueworx Voice Response if for some reason a transfer operation using Genesys CTI cannot be completed satisfactorily.

  See Enhanced Genesys CTI support for more information.

• Support for IPV6 IP addresses
• Java support upgraded to Version 6.0
  • Blueworx Voice Response for AIX Version 6.1 supports the use of Java Version 6.0 for Using CCXML, VoiceXML or Java applications.

  See Java support upgraded to Version 6.0 for more information.

• User-configurable logging for monitoring of VoiceXML and CCXML applications
  • Ability to configure VoiceXML and CCXML application logging to allow real-time monitoring of such applications.

  See User-configurable logging for monitoring of VoiceXML and CCXML applications for more information.

• Enhanced application support for SIP headers
  • In addition to Call-ID and Call-Info SIP headers, up to ten user-configurable SIP headers are now supported by VoiceXML and CCXML application call data session variables.

  See Enhanced application support for SIP headers for more information.

• Improved VRBE tracing

  See Additional VRBE problem determination utility for more information.

• Improved speech technology
  • Support for a secondary back-up server so that MRCP speech recognition and text-to-speech can continue in the event of a failure.
  • Support for speech recognition and text-to-speech using dynamic engine allocation, so that speech recognition and text-to-speech engines can be allocated only for the duration of each period of speech recognition or text-to-speech.
  • Support for MRCP-V1.0-compliant speech technologies such as Nuance Speech Server, Loquendo Speech Server, LumenVox, and WebSphere Voice Server.
  • State table applications can now access MRCP text-to-speech servers.
  • Additional ‘proprietary’ DTMF barge-in detection method.
