For C-series software upgrade including Quick Set C20 required software and release key (as Magnus advise earlier).
You may use following methods for getting TC4.x release key for your C20 software upgrade (to TC4.2.3).
1) Contact Cisco License Team (license@cisco.com) with your Endpoint Serial Number and service contract information. Cisco License Team will reply you with necessary information.
