Implementing and Operating Cisco Collaboration Core Technologies (CLCOR)

Business communication now spans desk phones, softphones, video rooms, mobile devices, and cloud meetings, and users expect every call and meeting to simply work. The Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) course gives IT professionals the skills to design, deploy, and run the Cisco collaboration platforms behind that experience, whether they sit on-premises, in the cloud, or across both.

Version 2.0 of the course reflects how organisations run collaboration today, with content balanced between on-premises and cloud. The first part, CLCOR-OP, covers Cisco Unified Communications Manager (CUCM) clustering, LDAP integration, device provisioning, dial plans, globalised call routing, calling privileges, Cisco Unity Connection, Cisco Expressway, Cisco Unified Border Element (CUBE) and media resources on Cisco IOS XE. The second part, CLCOR-HC, moves to the Webex Suite, Webex Calling dial plans and PSTN options, Cloud Connected UC, migration to the Webex App, collaboration APIs, and Quality of Service (QoS) on Cisco Catalyst switches.

Throughout the course, learners work in hands-on labs that mirror real deployments, from provisioning endpoints and building route patterns to tracing SIP signalling and fixing poor call quality. Security runs through every topic, including certificates, single sign-on, OAuth, encrypted media, and toll fraud prevention.

CLCOR is the official preparation for Cisco exam 350-801. Passing it earns the Cisco Certified Specialist – Collaboration Core credential and satisfies the core exam requirement for both CCNP Collaboration and CCIE Collaboration, making this course the foundation of every advanced Cisco collaboration career path.

By the end of this course, participants will be able to:

1. Explain Cisco collaboration architecture and select on-premises, hybrid or cloud deployment models designed for high availability.
2. Deploy and manage CUCM, including clustering, LDAP user synchronisation, device provisioning and role-based access control.
3. Build dial plans with globalised call routing, calling privileges and toll fraud prevention for both CUCM and Webex Calling.
4. Configure Cisco Unified Border Element, IOS XE voice gateways, and media resources to connect users to external networks.
5. Integrate Cisco Unity Connection for voicemail, message waiting indication, and automated call handling.
6. Deploy Webex services and Cloud Connected UC, and migrate users from Cisco Jabber to the Webex App.
7. Apply QoS classification, marking, and queuing, and troubleshoot signalling and media issues with confidence for the 350-801 exam.
