About this exam

The Cisco 300-815 CLACCM exam (Implementing Cisco Advanced Call Control and Mobility Services) is a concentration exam within Cisco's collaboration certification track. It targets voice and collaboration engineers who design, deploy, and troubleshoot advanced call control in Cisco Unified Communications Manager (CUCM) and related platforms. The exam spans five domains: Call Control and Dial Planning, Call Control and Mobility Services, Call Control and Mobility Troubleshooting, Mobility and Remote Access, and Security and Policy Enforcement. Expect scenario-based multiple-choice and multiple-response items plus drag-and-drop and simulation-style tasks that test hands-on configuration reasoning. To prepare, build a lab with CUCM, Cisco Unified Border Element (CUBE), and Cisco Expressway; practice translation patterns, route patterns, hunt groups, device mobility, extension mobility, and SIP normalization. Reinforce with Cisco's official exam topics and authorized training. This page is independent study material and is not affiliated with or endorsed by Cisco. Cisco publishes current exam logistics such as question count, time limit, fee, passing score, and retake policy on its official certification site; confirm those details there before scheduling.

What you'll study

Common questions

About Cisco 300-815 CLACCM preparation

What is the format of the 300-815 exam?

The exam uses multiple-choice and multiple-response questions, drag-and-drop items, and simulation or lab-style tasks that present a scenario and ask you to choose the correct configuration or troubleshoot a fault. Cisco publishes the authoritative format and current delivery details on its official certification site.

How difficult is CLACCM compared with other collaboration exams?

Candidates typically find it moderately challenging because it assumes working knowledge of CUCM dial plan components and SIP signaling. The troubleshooting domain is often the hardest. Hands-on lab practice with translation patterns, route groups, and SIP normalization reduces difficulty more than reading alone.

How long is the exam and how many questions are there?

Cisco does not guarantee a fixed number of questions or a fixed duration on this page. The official body publishes the current figure for question count and time limit on its certification website. Check that site before you schedule so you can plan your pacing.

What is the passing score and what does it cost?

Passing scores are scaled and set by Cisco; the current passing score and exam fee are published on Cisco's official certification site. This independent page does not state those figures because they change. Confirm the fee and passing standard there before booking.

Can I retake the exam if I fail?

Cisco defines retake rules, waiting periods, and any fees on its official certification site. The policy can change, so verify the current retake terms there before you schedule a second attempt. Plan your study time around the published waiting period.

In what order should I study the five domains?

Start with Call Control and Dial Planning because translation patterns, route patterns, and route groups underpin every other domain. Then study Mobility Services and Remote Access, followed by Security and Policy Enforcement. Finish with Troubleshooting so you can apply the earlier configuration knowledge to fault scenarios.

What are common failure modes on this exam?

Candidates often lose points on translation pattern versus route pattern precedence, digit manipulation order, and device mobility versus extension mobility distinctions. Weak SIP troubleshooting and unfamiliarity with CUBE dial peers also cause misses. Practice reading call flows and verifying your configuration in a lab.

Do I need lab equipment to prepare?

A lab greatly improves retention. A small CUCM cluster, Cisco Unified Border Element, and Cisco Expressway in a virtual environment let you test translation patterns, hunt groups, mobility, and SIP normalization. If hardware is unavailable, structured configuration exercises and call-flow tracing still build the needed reasoning.

How does this exam fit into certification?

CLACCM is a concentration exam that can satisfy the concentration requirement for collaboration certifications. Cisco defines which certifications accept it and any recertification rules on its official site. Verify the current certification path there because requirements change.

No. This is independent study material written for candidates preparing for the exam. It is not affiliated with, endorsed by, or sponsored by Cisco. Always confirm exam topics, logistics, and policies on Cisco's official certification site.
