Maintenance cycle

This section describes the Sinch Contact Pro maintenance policy for on-premise feature pack (FP) releases.

• Initial support period

  Each new release receives a minimum support period of 5 years from its release date.

• Impact of subsequent releases

  When a new release is introduced within the initial support period of a previous release, the support for the previous release is reduced to 24 months from the date of the new release.

• Multiple releases under maintenance

  Multiple releases are under maintenance simultaneously. Each release will have its support period adjusted based on the introduction of the subsequent release.

For the release dates, go to https://downloads.cc.sinch.com/.

If your version is out of maintenance, you can still get help from Sinch Contact Pro support. However, Sinch recommends updating your on-premise installation to ensure your contact center operations run on the latest release, or at least the second most recent one.

Note that once the support period ends, Sinch is not obligated to correct product issues for versions no longer under maintenance. This includes issues related to product security updates or technology changes. CVE (Common Vulnerabilities and Exposures) findings classified as high or critical (CVE score 7.0 or higher) are corrected only in versions under maintenance.
