# Add/Change Licenses

TelcoBridges uses a license-based approach to activate software or hardware functions in [Toolpack](/appendices/appendix-a-glossary/glossary-toolpack.md) or the underlying Telcobridges hardware. Whether you are installing Toolpack, implementing new software capabilities, or adding new hardware modules, you may be required to add or modify a license. The following instructions will enable you to do so.

IMPORTANT: You will need to reboot the telecom unit to activate the new license.

### Reference

* [Upload licence for Toolpack v3.2](https://docs.telcobridges.com/wiki/Toolpack:System_Settings_E#Upload_license)
