Pronexus Sunset Policy

Pronexus offers technical support for the most current version of our Interactive Voice Response (IVR) products, as well as the two previous versions. When a product or product version is scheduled for sunset, a notification will appear on this page indicating the date when the technical support will be discontinued.

After this date, Pronexus will offer support (including assistance and problem solving) for the current version, and two previous versions. However, Pronexus will only fix defects/bugs in the most current version, and will not propagate defect / bug fixes to previous releases.

Dialogic SR 5.1.1

Dialogic discontinued support for SR 5.1.1 on December 31st, 2007. Pronexus is therefore not able to provide support for this service release from January 1st, 2008 on. We will continue supporting only customers using SR 5.1.1 on Springware non-JCT cards and only for issues that are not related to Dialogic SR 5.1.1 problems.

If you have Dialogic SR 6.0 and above compatible voice boards and encounter a problem that is diagnosed to be Dialogic specific, you will be required to upgrade to Dialogic SR 6.0 and a higher version of VBVoice to continue resolution of your problem.

Also as of January 1st, 2008 Pronexus will no longer support configuration for voice boards not supported under Dialogic SR 6.0 and above.

End of Life Notices

  • Dialogic HMP 2.0 has not been available for purchase since September 2008. Support ended December 30, 2008. We recommend upgrading to HMP 3.0.
  • Nuance Speechify has been discontinued and can no longer be sold. We recommend using Nuance Realspeak instead, or looking into other options using MRCP with VBVoice 5.6.1.
