Cisco CCNP Advanced Call Control and Mobility Services (300-815 CLACCM) v1.2

Organizations running Cisco Collaboration need consistent call control skills across the team, not just one voice specialist who can troubleshoot CUCM or CUBE under pressure. This professional-level Cisco course is best assigned to network administrators, collaboration engineers, and voice-focused IT Practitioners with roughly three to five years of Cisco collaboration experience who support CUCM, CME, SRST, SIP trunks, dial peers, and call routing.

The course represents a meaningful time investment: the listed curriculum includes more than 35 hours of training, plus additional skills, so IT Directors and Training Managers should plan it as a multi-week enablement path rather than a quick exam cram. Because the topics include dial plans, SIP behavior, toll fraud prevention, TLS/SRTP, and call admission control, Team Leads should align practice with internal change-control standards before production changes.

CBT Nuggets can support rollout with Playlists to sequence assignments, Practice Exams for 300-815 readiness, Virtual Labs where available for hands-on reinforcement, and Team Reporting to track progress across the team.

This training helps collaboration teams reduce risk in Cisco voice environments by building shared fluency in call signaling, routing logic, survivability, and troubleshooting workflows. The curriculum maps to real operational scenarios that affect uptime, user experience, and security.

• Faster incident response: Teams practice interpreting SIP call flows, CUCM traces, call setup, media establishment, and mid-call signaling issues such as hold, resume, transfer, conferencing, DTMF, and session timers.
• Stronger branch resilience: SRST and advanced SRST topics help teams prepare remote sites to maintain telephony services during WAN or CUCM reachability issues.
• Cleaner call routing changes: CME dial plans, dial peers, CUCM route patterns, route lists, route groups, translation patterns, and transformations help standardize how calls are matched and routed.
• Reduced security exposure: CUBE toll fraud prevention, SIP profiles, registration-based SIP trunks, TLS, and SRTP give teams a framework for securing voice edge services.

Knowledge

• SIP call flow behavior, including early offer, delayed offer, early media, PRACK, UPDATE, and mid-call signaling.
• CUCM call control concepts such as digit analysis, route patterns, route lists, route groups, translation patterns, transformations, regions, and locations.
• CME and SRST concepts for local call processing, auto registration, dial plans, survivability, and remote-site telephony.
• CUBE concepts including dial peers, SIP-based trunks, SIP profiles, codec negotiation, DTMF relay, toll fraud prevention, TLS, and SRTP.
• Troubleshooting sources such as CUCM traces and call setup/media establishment indicators.

Ability

• Analyze SIP signaling to isolate call setup, media, transfer, conference, and DTMF issues.
• Configure and validate CME, SRST, dial peers, voice translation rules, and codec preference behavior.
• Build and troubleshoot CUCM routing components that affect enterprise call completion.
• Apply CUBE configuration patterns for SIP trunking, local gateway, multi-tenant, and provider-facing scenarios.
• Support 300-815 CLACCM exam preparation as part of the CCNP Collaboration certification path.
