300-815
Implementing Cisco Advanced Call Control and Mobility Services (CLACCM)
300-815 CLACC v2.0 Exam Guide: Skills, Blueprint, and Study Roadmap
Cisco 300-815 CLACC v2.0 validates advanced on-premises call-control implementation skills across signaling, media, gateways, session border controllers, mobility, security, and related collaboration services. It is intended for professionals working with Cisco collaboration environments and for candidates using a concentration exam toward CCNP Collaboration. The main decision is whether this on-premises focus matches your target role and, if it does, how to sequence blueprint study, hands-on practice, and official preparation before booking the exam.
What does 300-815 validate?
300-815 validates the ability to implement and troubleshoot advanced call-control services in on-premises Cisco collaboration environments. The v2.0 coverage includes signaling and media protocols, session border controller and voice gateway technologies, advanced call control, supplemental features and security, business-to-business solutions, and remote connectivity and mobility.
This is not simply a product-familiarity test. The official topic document points to technical work such as SIP troubleshooting, Cisco Unified Border Element, Cisco UCME, SIP SRST, SIP interoperability, call recording, globalized Unified Communications Manager routing, certificate management, and security. Those topics indicate a need to connect configuration decisions with call behavior, interoperability, and protection of the collaboration environment.
The title matters when you choose study material. Cisco currently identifies the exam as Implementing Cisco Advanced Call Control On-Premises (CLACC) v2.0. A resource focused only on cloud calling or general collaboration fundamentals will not, by itself, map cleanly to this exam’s advanced on-premises scope.
Which certification paths can it support?
Passing 300-815 earns the Cisco Certified Specialist – Collaboration Call Control & Mobility Implementation certification. Cisco also identifies the exam as a concentration option for CCNP Collaboration when combined with the required core exam. Candidates pursuing the professional certification should therefore plan the core and concentration requirements together rather than treating CLACC as the entire CCNP Collaboration path.
Who should consider it?
The exam is a sensible target for engineers, administrators, and implementation specialists whose work includes Cisco Unified Communications Manager call routing, SIP-connected systems, gateways, mobility, or on-premises collaboration security. It is less suitable as a first exposure to voice networking: the blueprint expects you to reason about interactions among signaling, routing, media, gateways, and security controls.
If your work is primarily cloud customer experience, Cisco has separately announced the 300-830 CLCCE specialist exam. If your goal is hybrid and cloud collaboration, compare that direction with the CLACC on-premises focus before committing to a study plan.
What changed between v1.2 and v2.0?
The version decision should come before study begins. Cisco announced that the last day to test on 300-815 v1.2 topics was February 2, 2026, and the first day to test on v2.0 topics was February 3, 2026. Cisco currently identifies 300-815 as v2.0, so candidates scheduling now should use the current v2.0 exam page and topic document.
Do not build a plan from an old outline simply because its title contains 300-815. Compare the version printed on every blueprint, course, practice lab, and note set. A mismatch can leave you overprepared for retired emphasis while leaving current subjects—such as STUN/TURN/ICE, certificate management, or updated security coverage—understudied.
The broader CCNP Collaboration update introduced a clearer distinction between on-premises and cloud-oriented specialization. That context is useful for choosing a path, but it does not replace the 300-815 v2.0 blueprint. Let the official topic document control your study scope.
A practical version-control check
Before paying for an attempt, open the official CLACC exam page and the v2.0 topic PDF. Record the exam title, version, listed domains, and any registration information shown there. Then audit your resources. Retire notes that refer only to v1.2 unless you can map each topic to the current blueprint and verify that the technical treatment remains relevant.
Which domains carry the most blueprint emphasis?
The official v2.0 topic document gives the clearest basis for prioritizing study. Session Border Controller and Voice Gateway Technologies carries 30%, Advanced Call Control carries 25%, Supplemental Features and Security carries 20%, and Signaling and Media Protocols carries 10% in the sections shown in that document. Business-to-business solutions and remote connectivity and mobility are also named as coverage areas, so do not treat the displayed percentages as a complete substitute for reading the full topic list.
Use the weights to allocate attention, not to predict a question count or a passing threshold. Cisco states that the exam is graded pass/fail, but the supplied official sources do not provide a passing score, question count, or scoring formula. A high-weight domain deserves more preparation time; it does not make lower-weight topics optional.
How should the percentages affect your schedule?
Start with Session Border Controller and Voice Gateway Technologies because it has the largest named allocation: 30% for that domain. Continue with Advanced Call Control at 25%, then Supplemental Features and Security at 20%, and Signaling and Media Protocols at 10%. After that first pass, return to the complete topic document and add study time for named areas that are not assigned a percentage in the supplied summary.
Avoid comparing bare percentages. Each figure belongs to its official domain: 30% is Session Border Controller and Voice Gateway Technologies, 25% is Advanced Call Control, 20% is Supplemental Features and Security, and 10% is Signaling and Media Protocols. Keeping the labels attached prevents an inaccurate impression of what the blueprint measures.
What should you know about the exam appointment?
Cisco lists the exam duration as 90 minutes, the price as US$300, and English as the available exam language. Cisco also states that results are available online within 48 hours and that the exam is graded pass/fail. Confirm the current registration and delivery information on Cisco’s exam page before scheduling, because the supplied sources do not establish a delivery method or every appointment rule.
The price and language are planning constraints, not study topics. If English is not your strongest technical reading language, practise reading configuration symptoms and protocol descriptions in English while studying. For timing, use the listed 90-minute duration to rehearse decision-making and review discipline, but do not assume a particular number of questions or a fixed time allowance per item.
Cisco states that 300-815 can be used toward recertification. Candidates who are choosing between certification activities should check Cisco’s current recertification rules and determine how this exam fits their existing certification plan. The CLACCM training page separately states that its training provides 40 Continuing Education credits toward recertification; those credits are a feature of that training, not a claim about exam performance.
What is not officially established here?
The supplied research does not verify delivery mode, question count, item formats, accommodations, rescheduling terms, or a passing score. Do not rely on forum summaries for those details when making a booking decision. Use Cisco’s current registration flow and exam page for appointment-specific information.
How should you study the technical blueprint?
Study by call flow and failure domain rather than memorizing isolated feature names. For each blueprint topic, write down the traffic path, the component responsible for the decision, the expected signaling or media behavior, the evidence that confirms it, and the security or interoperability consequence. This method turns a long topic list into troubleshooting decisions you can practise.
A useful sequence is protocol foundation first, gateways and border control second, advanced routing and mobility third, and supplemental features and security fourth. Then revisit the topics by scenario. For example, a SIP failure may involve signaling syntax, a border element policy, a gateway dial peer, certificate trust, or a routing transformation. The exam’s value lies in distinguishing those causes, not in recalling a command without context.
Phase one: build the protocol model
Begin with Signaling and Media Protocols, the domain allocated 10% in the official sections shown. Review SIP message flow, media negotiation, and the role of STUN, TURN, and ICE. Pair each concept with a symptom: a call that never establishes, a call that connects without audio, or media that works in one network path but fails through another.
Create a one-page evidence table. Include the symptom, the signaling stage involved, the likely component, the log or trace that would confirm the hypothesis, and the corrective direction. This is a study aid, not a substitute for Cisco documentation or a live lab. Its purpose is to force precise reasoning before you touch configuration.
Phase two: practise gateways and border control
Session Border Controller and Voice Gateway Technologies carries 30% in the official blueprint sections shown, the largest named allocation. Give this domain the most lab and troubleshooting time. Include Cisco Unified Border Element, Cisco UCME, and SIP SRST in your plan, and trace how calls enter, are matched, transformed, routed, and returned.
Do not study a border element as an isolated box. Draw both directions of a call and mark trust boundaries, address translation, codec or media decisions, number manipulation, and failover behavior. Test one change at a time and record the original symptom, the hypothesis, the configuration change, and the evidence that the change worked. This record exposes assumptions that flashcards tend to hide.
Phase three: organise advanced call control
Advanced Call Control carries 25% in the official blueprint sections shown. Review globalized UCM routing and the relationships among partitions, calling search spaces, route patterns, route lists, route groups, transformations, and gateway selection. Include mobility behavior and the way a routing decision can change when a user, endpoint, or trunk is in a different context.
Use small, deliberate scenarios rather than a single large topology. Start with a local call, add international or globalized numbering, then introduce an alternate route or a mobility condition. After each change, state which object should make the decision and why. If the result differs from your expectation, troubleshoot the decision path instead of changing several settings at once.
Phase four: integrate supplemental features and security
Supplemental Features and Security carries 20% in the official blueprint sections shown. Include call recording, certificate management, and security in the same study cycle as call control. Ask what must be trusted, what must be authenticated, which connection or media path is protected, and what operational symptom appears when a certificate or policy is wrong.
The integration matters. A secure SIP connection can fail before routing is evaluated; a recording requirement can alter media handling; and a certificate problem can resemble a reachability or interoperability problem. Build comparison notes that distinguish transport, identity, signaling, media, and application behavior. That separation is more useful than a list of security product names.
What hands-on practice is worth the effort?
The most valuable lab work reproduces a decision and then breaks one dependency. Build or use an environment where you can observe SIP signaling, routing choices, gateway or border-element behavior, mobility, and certificate-related failures. The supplied sources do not promise a lab exam or specify required equipment, so treat a lab as a practical recommendation rather than an official requirement.
For every exercise, begin with a working baseline. Capture the expected route, signaling sequence, media path, and security assumptions. Change one variable, reproduce the issue, collect evidence, restore the baseline, and explain the fix. This cycle develops a diagnostic habit that is difficult to gain from answer memorization and remains useful after certification.
Suggested scenario set
Use a SIP interoperability scenario to compare expected and actual headers or negotiation. Use a Cisco Unified Border Element scenario to examine trust boundaries and call admission decisions. Use a Cisco UCME or SIP SRST scenario to test local or survivable calling behavior. Use a globalized UCM routing scenario to trace number normalization and route selection. Finally, add call recording or certificate management and observe how the feature changes the call path or failure evidence.
Keep a lab journal with topology, versions, assumptions, commands or interface views used for observation, and the conclusion. Do not copy configurations without understanding the reason for each element. If you cannot explain why a route, gateway, policy, or certificate is involved, mark that topic for another study pass.
How can you turn the topic list into a study plan?
A four-stage roadmap works well when you have not yet measured your gaps: map the blueprint, learn the mechanisms, troubleshoot integrated scenarios, and validate readiness. Set the length of each stage according to your available time and current experience rather than copying an arbitrary calendar. The official sources establish the scope, but they do not prescribe a preparation duration.
At the start, download the current v2.0 topic document and create a matrix with one row per topic. Mark each row as explain, configure, troubleshoot, or review. A topic is not ready merely because you recognize its name. You should be able to describe its purpose, identify dependencies, and interpret a failure symptom without consulting a memorized answer.
Stage one: map and baseline
Read the official topic document once without trying to memorize it. Highlight terms that are familiar, partly familiar, and new. Then perform a baseline exercise: explain a basic SIP call path, trace a routing decision, and identify where a border controller or gateway can affect the call. Record gaps honestly. Your first objective is scope control, not speed.
Stage two: learn by mechanism
Study the largest named domains first, while maintaining coverage of every listed area. For each mechanism, create a short explanation and a diagram or decision tree. Connect SIP troubleshooting to the component that can produce the symptom; connect certificate management to trust and identity; connect mobility to reachability, routing, and user behavior. Revisit the 30% Session Border Controller and Voice Gateway Technologies domain, the 25% Advanced Call Control domain, the 20% Supplemental Features and Security domain, and the 10% Signaling and Media Protocols domain with their labels intact.
Stage three: integrate and troubleshoot
Replace isolated reading with mixed scenarios. Start with a symptom and work toward evidence: identify whether the failure is signaling, media, routing, gateway, border-control, feature, or security related. Add a second dependency only after the first diagnosis is defensible. This prevents a common mistake—changing several settings until the call works without knowing which change solved the problem.
Stage four: validate readiness
Use the official topic list as a final audit. For every topic, explain the concept aloud or in writing, identify the relevant configuration area, and describe how you would verify a failure. A practice question can reveal a gap, but it should lead to documentation and lab work rather than answer memorization. Do not treat exam dumps or leaked-question claims as legitimate preparation or as a guarantee of passing.
Run a timed review using the listed 90-minute exam duration as your rehearsal boundary. Practise moving past an item that requires too much thought, recording the issue for later review, and returning with a clearer method. This is a time-management recommendation; Cisco’s supplied materials do not specify question count or item format.
Which preparation mistakes should you avoid?
The most damaging mistake is studying the wrong version. The next is treating a high-level product list as proof of readiness. 300-815 v2.0 spans protocols, routing, gateways, border control, mobility, features, and security, so a candidate who can recite terminology but cannot trace a call or isolate a failure has a fragile preparation base.
A third mistake is using blueprint percentages as a pass prediction. The 30% Session Border Controller and Voice Gateway Technologies domain is important, but the official sources do not say that mastering it guarantees a pass. Likewise, the 10% Signaling and Media Protocols domain still matters because protocol errors can explain failures in several other scenarios.
Avoid neglecting interoperability and security because your current job is narrowly focused. The official topic document explicitly includes SIP interoperability, business-to-business solutions, certificate management, and security. You may not use every feature daily, but you should know where it belongs in a call path and how to investigate it.
Finally, do not let a course completion certificate replace evidence of skill. Cisco’s CLACCM training page says the training prepares candidates for 300-815 and provides 40 Continuing Education credits toward recertification. Those benefits do not remove the need to study the blueprint, practise configuration reasoning, and verify weak areas.
A quick self-audit before booking
You are closer to ready when you can map a symptom to a likely layer, justify a routing or gateway decision, explain the purpose of the relevant security control, and identify what evidence would confirm your diagnosis. If your answers depend on remembering a particular practice-test response, postpone the appointment and return to the mechanism behind that response.
What should you do before scheduling?
Confirm that your target is the current 300-815 CLACC v2.0 exam and that its on-premises emphasis matches your role or certification plan. Read the official v2.0 topics, check Cisco’s current exam page for registration details, and decide whether you need the exam for the specialist certification, the CCNP Collaboration concentration requirement, recertification, or more than one of those purposes.
Next, build the topic matrix and assign your first study block to the largest named domain: Session Border Controller and Voice Gateway Technologies at 30% in the official sections shown. Add a lab or troubleshooting task for every major study area, then schedule a readiness review rather than booking solely because you have finished a course.
At the appointment stage, budget for Cisco’s listed US$300 price, plan around the listed 90-minute duration, and prepare for the available English exam language. Confirm those details directly with Cisco before purchase. After testing, Cisco states that the result is graded pass/fail and available online within 48 hours; keep the official result and any recertification records with your certification plan.
Official resources to open first
Use the Cisco CLACC exam page for the current title, price, language, duration, and registration context. Use the v2.0 topic PDF as the study boundary. Use Cisco’s CCNP Collaboration exams-and-training page to confirm how the concentration exam relates to the required core exam. Treat the CLACCM course page as a training option and review its stated Continuing Education credit information separately from exam requirements.
Conclusion
A sound 300-815 plan is built around the current v2.0 blueprint, not a collection of remembered answers. Confirm the version, choose the on-premises path deliberately, prioritise the named blueprint domains, and practise tracing real call-control decisions through protocols, gateways, border control, routing, mobility, features, and security. Before scheduling, verify Cisco’s live appointment information and use a topic-by-topic readiness audit to identify what still needs explanation or hands-on troubleshooting.
