About
CLACCM (Call Manager Advanced) is a concentration exam for CCNP Collaboration certification, focusing on advanced Cisco Unified Communications Manager (CUCM) administration, call control, and enterprise mobility features. Released in 2020 as part of the modernized CCNP Collaboration track, CLACCM validates deep expertise in dial plan architecture, advanced routing, CUCM clustering, media resources, gateway protocols, and mobility services. Candidates must hold or concurrently earn CLCOR (350-801) to obtain CCNP Collaboration. CLACCM targets senior collaboration engineers and UC architects managing enterprise-scale CUCM deployments, multisite environments, and advanced call routing scenarios.
Domain context — Networking / Voice & Unified Communications
Voice and unified communications infrastructure spanning session initiation protocol (SIP), media transport, advanced call control, and enterprise mobility. Focus on call routing complexity, multisite deployments, gateway integration, and cloud-hybrid architectures with advanced CUCM features.
