Webex Calling · Cloud and hybrid
Why our webex calling training
Labs connect Webex Calling to a premises CUBE Local Gateway and a CUCM cluster.
Cloud and hybrid services make up around a quarter of CLCOR v2.0.
Coexistence and migration patterns from engineers who have run them at scale.
What you'll learn
Hands-on
Plan, deploy and operate Webex Calling: Control Hub, locations, numbering, Local Gateway, cloud PSTN and coexistence with CUCM.

FAQ
Yes. You'll deploy a register-based Local Gateway on CUBE and route calls between Webex Calling, CUCM and the PSTN.
Yes. Cloud and hybrid services, including Webex Calling, are a major domain in CLCOR v2.0 and central to CLHCT 300-820.
