Two types of Cisco Unified Border Element licenses are available:

- Pay-as-You-Grow, or session count, license
- Platform, or flat, license

Cisco Unified Border Element licenses are available in both types on select platforms. Cisco Gatekeeper licenses are available in the platform license type only.

Pay-as-You-Grow License

This type of license covers the right to use the feature as well as the maximum session count allowed. An example is the FL-CUBE-25 license, which allows up to 25 sessions.

This license is designed to allow a specific number of sessions (or calls) on a platform. Purchase only as many sessions as are required in your deployment. You can add more licenses later as your needs expand, thus offering pay-as-you-grow benefits. Session licenses are stackable. These licenses are available on select platforms as given in Table 3, and are available on all software images. Examples include the FL-CUBE-4 and FL-CUBEE-100 licenses.

Platform License

This type of license covers the right to use the feature up to the maximum session count supported on the chosen platform as given later in the document in Table 6. An example is the FL-INTVVSRV-2811 license, which allows the maximum number of sessions the Cisco 2811 platform supports.

These licenses are available on select platforms as given in Table 3. These licenses require a software image with C or D feature capability as given in Table 1. Examples include the FL-INTVVSRV-2801 and FL-GK-3945 licenses.
