Features of VBVoice 10.1 include:

  • Visual IVR flows much like a voice call; no need for the end user to press "enter" when entering their information
  • Visual IVR menus can offer more than one method of data input in the same menu, e.g. selecting from a list of menu option or inputting a name into a text box if the desired option does not appear
  • Visual IVR end users can listen to a voice prompt if desired when using the visual channel
  • Dynamic menus can be turned on and off at runtime without recompiling and redeploying the application
  • All VBVoice support assemblies for .net are now stored in one library

VBVoice 8.20

VBVoice 8.20 features are still contained in the release of VBVoice 10.

Integration into Unified messaging through Microsoft Lync

Microsoft Lync Interoperability allows developers to build enterprise class unified messaging systems and to create and integrate IVR applications by using the VBVoice toolkit. As a long-standing Microsoft Partner, Pronexus is committed to keeping pace with the power of the Microsoft platform, ensuring its customers’ compatibility with the full potential of Microsoft’s tools.


Interoperability Secure media through SRTP

Secure RTP is now embedded in VBVoice 8.20 eliminating the risk of eaves-dropping on IVR solutions using carrier-grade secure media. In the past, SIP calls travelling through public networks allowed the audio conversations and data transmitted during the call (including any digits entered such as PINs, or credit card information) to be easily intercepted. Now, Secure RTP (SRTP) will encrypt all audio streams making all the information passed during a call inaccessible to possible attempts to tap into the call.


Proprietary call control functionality for SIP, replacing the need for third party call control.

Pronexus now offers its own optional proprietary SIP call control for VBVoice customers in the 8.20 version. Eliminating the need for third party call control, developers can now reduce the cost of their application and make use of the proprietary Pronexus Call Control. The new Pronexus Call Control eliminates the limitations inherent in using a third party solution, and provides a foundation for adding additional features in future VBVoice releases, such as support for transfers through re-invite messages, support for changes of codecs and other call conditions during the call, and the ability to expose more information about the call to the application.
