300-815 CLACCM
This CCNP Collaboration training prepares learners to take the 300-815 CLACCM v1.2 exam, which is one of the concentration exams required to earn the CCNP Collaboration certification. Cisco's telephony, VoIP and collaboration networks do a lot of heavy lifting for collaboration engineers and network administrators, but advanced configurations of a Cisco phone network still require detailed technical knowledge and experience. Use this training as 300-815 CLACCM exam prep, and prove your mastery of calls and mobility services.

CCT Collaboration
This Cisco CCT Collaboration training prepares field engineers and technicians to support Cisco collaboration environments from day one. It covers the Voice over IP (VoIP) concepts behind Cisco voice and video, the differences between Cisco Webex hardware components, how to work in Cisco Unified Communications Manager (CUCM), and the network tools used across data, voice, and video infrastructure. For an IT Director staffing a support or field team, this is the baseline: technicians who finish it can troubleshoot VoIP issues and maintain Webex hardware without escalating routine work. Cisco retired the 100-890 CLTECH exam on 9 February 2025, so the course is assigned today for those skills.

Cisco CCNP Collaboration Core (350-801 CLCOR)
Collaboration outages, poor call quality, expired or misconfigured certificates, and loose dial-plan controls create real business risk for organizations that run on Cisco Unified Communications. This intermediate course gives collaboration teams a shared, protocol-level understanding of how CUCM, Webex App calling, SIP, QoS, and secure media work together. It also covers how to keep these systems stable. Built for collaboration engineers, voice specialists, and senior support staff, the training covers high availability, disaster recovery, and CUCM upgrades. It also covers X.509 certificates, LDAP and SSO integration, SRTP, endpoint provisioning, call routing, and toll fraud prevention. Learners finish able to configure dial-plan components, deploy endpoints manually or in bulk, and build QoS policies. They can also troubleshoot DNS, NTP, LDAP, DHCP, registration, SIP call flow, and dial-plan issues using RTMT traces. At roughly 63 hours, this is a substantial investment that IT Directors and Training Managers can phase by operational domain: security, routing, endpoint deployment, troubleshooting, and QoS. Virtual Labs provide hands-on QoS practice with class maps, policy maps, policing, shaping, and WRED. Playlists and Team Reporting help leaders sequence modules and track completion across the team.
