From 3 February 2026, CLCOR v2.0 balances on-premises call control with cloud and hybrid services. Jabber and Skinny are out; the Webex App, Webex Calling and Expressway-based hybrid designs are in.
This course follows the v2.0 blueprint domain by domain. Every topic pairs a concept lesson with a hands-on lab on a real CUCM 15, CUBE and Expressway topology.
42 h video + 40 h labs, about 10 weeks at 6–8 hours per week.
