Implementing and Operating Cisco Collaboration Core Technologies (350-801 CLCOR)

When a call fails, a meeting freezes, or a phone refuses to register, users need an engineer who can find the cause quickly and fix it properly. The Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) course develops exactly that engineer. It is a practical, configuration-focused programme that takes you inside the systems carrying voice, video and messaging across modern organisations.

The course concentrates on the work collaboration engineers do every day. You design dial plans in Cisco Unified Communications Manager (CUCM), using route patterns, route groups, translation patterns, partitions and calling search spaces to deliver globalised call routing. You configure dial peers, voice translation rules and codec preferences on Cisco IOS XE gateways and Cisco Unified Border Element (CUBE), and set up DSPs, transcoders and recording as media resources. In the cloud, you apply the same discipline to Webex Calling dial plans, trunks and call permissions.

Troubleshooting is the thread that ties every module together. You learn to read SIP call flows and SDP negotiations, diagnose DTMF and registration failures, verify certificates and TLS handshakes, and track down the causes of one-way audio, choppy voice and video artefacts. Quality of Service design, from trust boundaries to low-latency queuing, gives you the tools to prevent many of these problems before they reach users.

CLCOR is the recommended preparation for Cisco exam 350-801, which validates these skills and serves as the core exam for CCNP Collaboration and CCIE Collaboration. You finish the course with lab-tested methods you can apply on the job immediately. We run this Cisco Collaboration training for engineers and IT teams across Oman.

After completing this training, you will be able to:

• Design and implement CUCM dial plans using route patterns, route lists, translation patterns, partitions, and calling search spaces.
• Configure Cisco IOS XE voice gateways and CUBE with dial peers, voice translation rules, codec preference lists and SIP profiles.
• Plan and deploy media resources, including DSPs, transcoders and call recording.
• Analyse SIP and SDP call flows to resolve call setup, DTMF, hold, transfer, and registration problems.
• Troubleshoot infrastructure dependencies such as DNS, NTP, DHCP, LDAP, certificates, and TLS.
• Build and verify Webex Calling dial plans, trunks, route groups, and call permissions.
• Diagnose media quality issues and implement classification, marking, and low-latency queuing policies.
