CLHCT 300-820 v2.0 replaces the previous Cloud and Edge exam and reflects how most organisations now run collaboration: some on-premises, some in Webex.
You will build Expressway-C and Expressway-E pairs, secure MRA and B2B calling with certificates, and connect on-premises CUCM to Webex Calling and hybrid services.
28 h video + 30 h labs, about 7 weeks at 6–8 hours per week.

“Finally an Expressway course that explains certificates properly. MRA worked first time in production afterwards.”
“Great Webex Calling coverage. The hybrid design module helped shape our migration plan.”
A deep dive into the Cisco collaboration edge: Expressway-C/E design, certificates, Mobile and Remote Access, B2B calling and hybrid connectivity.
Supports 300-820 CLHCT
Plan, deploy and operate Webex Calling: Control Hub, locations, numbering, Local Gateway, cloud PSTN and coexistence with CUCM.
