Contact Center Enterprise Software Release Delivery Model

Cisco introduces a new software release delivery model for Contact Center Enterprise products. Starting from Release 12.6(1), Contact Center Enterprise issues two types of releases:

  • Long Term Release (LTR)

  • Dynamic Release (DR)

We recommend the LTR delivery model if you prefer infrequent upgrade cycles over faster adoption of new features. This model includes support for bug fixes through engineering specials.

We recommend the DR delivery model if you want faster feature adoption. With this model, both new feature and bug fixes are delivered through engineering specials and maintenance releases. This model also offers simplified patch upgrades through automated notification, orchestrated patch application, and minimal downtime.

For more information about the new delivery models, see the product bulletin Cisco's Contact Center Enterprise Software Release and Sustaining Lifecycle. Release 12.6 is a dynamic release and will follow the sustaining process as outlined in this product bulletin.
