300-815 CLACC v2.0 Exam Guide: Skills, Blueprint, and Study Roadmap
The 300-815 CLACC v2.0 exam validates advanced on-premises call-control and mobility implementation skills across signaling, voice gateways, session border control, supplemental features, and security. It is aimed at collaboration professionals who design, configure, troubleshoot, or support Cisco voice environments. This guide helps you decide whether CLACC fits your CCNP Collaboration plan, confirm which version applies to your timeline, prioritize the blueprint, and build a study sequence based on configuration reasoning rather than memorized answers.
What does 300-815 CLACC validate?
300-815, titled Implementing Cisco Advanced Call Control On-Premises (CLACC) v2.0, focuses on the advanced call-control work that sits beyond basic collaboration deployment. The official v2.0 topics include 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.
The exam is therefore best treated as an implementation-and-troubleshooting assessment. A candidate should be able to connect symptoms to signaling behavior, routing logic, gateway or border-controller configuration, media traversal, interoperability requirements, and security controls. Reading a feature description is not enough; preparation should explain why a call takes a particular path and what changes when a signaling, media, certificate, or policy condition fails.
Cisco associates 300-815 with the CCNP Collaboration certification. Passing it earns the Cisco Certified Specialist – Collaboration Call Control & Mobility Implementation certification. The exam can serve as the CCNP Collaboration concentration exam requirement when combined with the required core exam. Those are separate outcomes: passing the concentration exam does not, by itself, establish the complete CCNP Collaboration certification.
Who should choose this exam?
CLACC is a logical choice for a collaboration engineer or administrator whose work includes Cisco on-premises call control, SIP connectivity, voice gateways, Cisco Unified Border Element, mobility, or advanced calling features. It also suits a CCNP Collaboration candidate who wants an on-premises concentration rather than a cloud-focused specialization.
Experience with only endpoint provisioning or routine user administration may not cover the full scope. The blueprint reaches into SIP troubleshooting, STUN/TURN/ICE, Cisco UCME and SIP SRST, SIP interoperability, call recording, globalized UCM routing, certificate management, and security. Before booking, compare those subjects with your actual responsibilities and identify which areas require lab time rather than reading alone.
Choose the exam because its technical scope matches your target role and certification plan, not because its code resembles another collaboration exam. The core exam and CLACC have different purposes. Use the official CCNP Collaboration exam information to verify the current combination requirements before registering.
Which exam version and timeline apply?
The current Cisco title is Implementing Cisco Advanced Call Control On-Premises (CLACC) v2.0. 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. A candidate scheduling around a version change should use the v2.0 topic document as the controlling study outline for the current exam.
This matters because studying an older outline can leave gaps even when the exam code remains 300-815. Cisco’s update describes v2.0 as part of a broader CCNP Collaboration change that separates cloud and on-premises emphasis. Do not assume that a legacy course, old notes, or an old practice resource reflects the current blueprint.
The practical decision is straightforward: if your test date is on or after February 3, 2026, organize preparation around the official v2.0 topics. If you are investigating an earlier historical attempt or an existing result, confirm the applicable policy and version directly with Cisco. Version status and registration information can change, so check the official exam page before committing money or a test date.
How is the v2.0 blueprint weighted?
Use the published domain weights to allocate study effort, but do not treat them as a promise about the exact number or format of questions. The v2.0 topic document allocates 10% to Signaling and Media Protocols, 30% to Session Border Controller and Voice Gateway Technologies, 25% to Advanced Call Control, and 20% to Supplemental Features and Security in the sections shown in that document.
Session Border Controller and Voice Gateway Technologies is the largest named allocation at 30%, so it deserves the deepest configuration and troubleshooting practice. Advanced Call Control carries 25%, while Supplemental Features and Security carries 20%; Signaling and Media Protocols carries 10%. Keep each percentage attached to its official domain when using the blueprint to plan time.
The listed allocations total less than the entire blueprint shown in the supplied evidence. That is a reason to avoid inventing a missing category or redistributing the remainder. Treat the official PDF’s complete topic list as authoritative, and use the named weights as prioritization signals rather than as a substitute for reading every objective.
A sensible allocation method is to give the largest block the most lab cycles, then schedule dedicated review for the next two domains. Do not abandon the 10% Signaling and Media Protocols domain: protocol fundamentals often explain failures in larger gateway, border-control, and call-control scenarios. A smaller percentage does not mean a topic is optional.
What technical areas need the most attention?
The most productive preparation connects each blueprint area to a call flow. Start with signaling and media behavior, then trace how routing, gateway or border-controller policy, interoperability, mobility, and security alter that flow. This prevents isolated memorization of commands and makes troubleshooting decisions easier to justify.
Signaling and Media Protocols includes SIP troubleshooting and STUN/TURN/ICE in the supplied v2.0 topics. Study the distinction between signaling reachability and media reachability. Build a troubleshooting checklist that asks whether messages arrive, whether the dialog progresses correctly, whether addresses and ports are usable across the path, and whether a traversal mechanism changes the media route.
Session Border Controller and Voice Gateway Technologies includes Cisco Unified Border Element, Cisco UCME, and SIP SRST. Prepare by drawing inbound and outbound call paths, identifying trust boundaries, and mapping where translation, normalization, routing, failover, and survivability decisions occur. For each design, record the expected signaling path and the expected media path separately.
Advanced Call Control includes globalized UCM routing and related call-control decisions. Practice analyzing number normalization, route selection, digit manipulation, and the effect of local versus globalized numbering. The goal is to predict the selected route and identify which stage introduced an incorrect number or policy result.
Supplemental Features and Security includes subjects such as call recording, certificate management, and security. Study these as operational dependencies, not isolated checkboxes. Ask what must be trusted, which component initiates the connection, what happens when a certificate is invalid or expired, and how a security control affects a legitimate call or recording workflow.
The blueprint also names business-to-business solutions and remote connectivity and mobility. Connect those subjects to the same method: identify the parties, signaling boundary, media path, authentication or trust requirement, routing decision, and failure evidence. A feature becomes exam-ready when you can explain both its intended operation and its likely failure points.
Which official details affect scheduling?
Cisco lists the 300-815 exam duration as 90 minutes, the available exam language as English, and the price as US$300, with Cisco Learning Credits also accepted. Cisco states that the exam is graded pass/fail and that results are available online within 48 hours. Confirm these details on the official exam page before registration because scheduling and commercial information can change.
The supplied evidence does not establish a delivery method, testing location, appointment process, rescheduling rule, or identification requirement. Do not rely on an unofficial listing for those details. Use Cisco’s current registration information and the provider’s instructions when you are ready to schedule.
Cisco states that 300-815 can be used toward recertification. Cisco’s CLACCM training page says that the training prepares candidates for the 300-815 CLACC exam and provides 40 Continuing Education credits toward recertification. Treat exam credit and training credit as separate mechanisms, and verify the current recertification rules before choosing a training option.
How should you assess your starting point?
Begin with a topic-by-topic inventory, not a general confidence rating. Mark each objective as can explain, can configure, can troubleshoot, or unfamiliar. A candidate who can describe SIP terminology but cannot trace a failed dialog should classify that area as a lab gap, not as mastered knowledge.
Create four columns in a study sheet: official topic, evidence of competence, unresolved question, and next practice action. Use the v2.0 PDF for the first column. In the second, record a configuration you built, a fault you diagnosed, or a call flow you can draw. In the third, write precise questions such as which component changes the route or why media cannot traverse a boundary.
Set an entry checkpoint before buying additional material. Attempt to explain a basic call path involving call control, a gateway or border controller, signaling, media, and a security dependency. If the explanation stops at product names, start with fundamentals. If you can trace the path but struggle with advanced features, prioritize targeted labs and troubleshooting notes.
Do not use a high score on a memory-based quiz as proof of readiness. Practice questions can reveal terminology gaps, but they cannot replace configuration reasoning. In particular, avoid resources that claim to reproduce live exam content or present memorized answers as a guaranteed route to passing.
What is an efficient study sequence?
Study in dependency order: protocol behavior first, then gateway and border-controller paths, then advanced routing and features, and finally security and integrated troubleshooting. This sequence gives later topics a working foundation. Reorder it only when your job requires an urgent weakness to be addressed first.
Phase one is a protocol and call-flow pass. Review SIP transactions, dialog progression, signaling versus media, and STUN/TURN/ICE concepts. For every scenario, draw the participants and label what each side knows about the other side’s address, transport, and media. Write down the evidence that would distinguish a signaling failure from a media failure.
Phase two is the gateway and border-control block. Work through Cisco Unified Border Element, Cisco UCME, and SIP SRST topics named in the blueprint. Build small scenarios rather than one complicated topology: a normal call, a rejected call, a survivability event, and an interoperability case. After each scenario, change one condition and predict the result before checking the behavior.
Phase three is advanced call control. Concentrate on globalized UCM routing, numbering, route selection, and mobility-related decisions. Use a table showing the original number, each transformation, the selected route, and the expected destination. This makes hidden assumptions visible and helps prevent the common mistake of treating every routing problem as a gateway problem.
Phase four covers supplemental features and security. Add call recording, certificate management, and security controls to an otherwise working call path. Intentionally introduce a trust or policy problem and document the observable symptom, the likely boundary, and the corrective decision. This creates a troubleshooting habit instead of a list of definitions.
Phase five is integration and review. Combine several domains in one scenario and explain the call from endpoint to endpoint. Then revisit the official topic PDF and mark every objective with evidence. Any unmarked objective becomes a final study task, regardless of how comfortable the larger domain feels.
What should a practical lab session look like?
A useful lab session has a defined call-flow question, a controlled change, and written evidence. Configure the smallest topology that can demonstrate the behavior, test a known-good call, introduce one fault, and isolate the fault by observing signaling, media, routing, or trust. The value comes from the diagnosis record, not from collecting complex topologies.
For each session, write five lines before you start: the intended call path, the expected signaling behavior, the expected media behavior, the policy or trust dependency, and the evidence that would prove failure at each stage. This forces you to make a prediction rather than react to output without a model.
Use scenario variations to test understanding. Change a number format and determine whether the issue is normalization or route selection. Change a boundary condition and determine whether the issue is signaling reachability or media traversal. Change a trust condition and determine whether the feature fails before or after call setup. Keep the change isolated so the result remains interpretable.
Finish by writing a short incident note: symptom, confirmed scope, rejected hypotheses, root cause, correction, and regression test. Revisit these notes during review. They become more useful than unstructured command lists because they preserve the reasoning that connected evidence to action.
Where you do not have access to a live environment, use architecture diagrams, official configuration references, and controlled mental walkthroughs. Be explicit that this is a conceptual exercise. Do not claim that reading a configuration example proves hands-on competence, and do not infer undocumented command behavior from a third-party answer.
How can you manage a 90-minute exam?
Cisco lists the exam duration as 90 minutes, so preparation should include concise technical reasoning. The aim is not to rush every item; it is to avoid spending an excessive amount of time reconstructing fundamentals that should already be familiar. Practice identifying the domain, the relevant call-flow stage, and the strongest evidence before choosing an answer.
Use a three-pass approach if the exam interface permits it: answer clear items first, flag items that require careful comparison, and return to uncertain items with the blueprint model in mind. This is a practical recommendation, not an official exam-interface rule; confirm available navigation behavior in Cisco’s current exam information.
For a scenario involving SIP, a gateway, or a border controller, name the failure layer before evaluating remedies. Is the issue signaling, media, routing, interoperability, survivability, recording, or trust? Then eliminate solutions that operate outside that layer. This reduces the temptation to select a familiar feature simply because it appears in the answer choices.
Budget attention for reading precision. Distinguish a requirement from an observed symptom, an inbound path from an outbound path, and a call-control result from a media result. When two options seem plausible, return to the stated topology and determine which component has authority over the behavior described.
Cisco states that the exam is graded pass/fail and that results are available online within 48 hours. Since no passing score is supplied in the official evidence here, do not set a target percentage or infer one from practice tests. Measure readiness by objective coverage and repeatable troubleshooting explanations instead.
Which preparation mistakes create avoidable gaps?
The most damaging mistake is studying the exam code without confirming the version and official topic document. A candidate can spend substantial time on legacy objectives while missing v2.0 subjects. Make version confirmation the first administrative task and repeat it shortly before scheduling.
Another mistake is treating the largest blueprint domain as the only domain that matters. Session Border Controller and Voice Gateway Technologies carries 30%, but Signaling and Media Protocols carries 10%, Advanced Call Control carries 25%, and Supplemental Features and Security carries 20% in the named sections of the official v2.0 blueprint. Each percentage belongs to its labeled domain, and every official objective still requires review.
Memorizing isolated commands is a weak substitute for understanding dependencies. A command may be correct in one topology and irrelevant in another. Study the role of the component, the direction of the call, the expected signaling and media behavior, and the security or interoperability condition before committing syntax to memory.
Ignoring negative testing is another common gap. Candidates often practice only a successful call and then recognize product terminology without knowing how failure appears. Introduce one controlled fault at a time and record what evidence changes. Troubleshooting practice should include failed setup, one-way or missing media, incorrect routing, survivability behavior, and certificate or policy problems where the lab supports them.
Finally, do not confuse training attendance, practice-question familiarity, or a previous certification with coverage of this blueprint. The CLACCM page identifies training that prepares candidates for 300-815 and offers 40 Continuing Education credits toward recertification, but training is not the same as an exam result. Validate each objective independently.
What should a four-stage roadmap include?
A practical roadmap should end with evidence for every objective, not merely a completed course. Use four stages: scope, foundation, implementation practice, and readiness review. The length of each stage should reflect your background and lab access; the supplied official sources do not prescribe a required preparation duration.
Stage one, scope, starts with the official v2.0 PDF and the exam page. Confirm the title, version, language, duration, price, certification relationship, and recertification relevance. List every named topic and classify your experience. At this stage, also decide whether you are pursuing the CCNP Collaboration concentration path or the specialist certification outcome.
Stage two, foundation, covers signaling and media behavior plus call-flow diagrams. Review SIP troubleshooting and STUN/TURN/ICE, then test whether you can distinguish signaling reachability from media traversal. Produce a one-page diagnostic model and use it for every subsequent lab or design exercise.
Stage three, implementation practice, gives most time to the 30% Session Border Controller and Voice Gateway Technologies domain and then to the 25% Advanced Call Control and 20% Supplemental Features and Security domains. Keep the official domain labels attached to those weights in your plan. Add scenarios involving Cisco Unified Border Element, Cisco UCME, SIP SRST, globalized routing, call recording, certificate management, interoperability, and mobility.
Stage four, readiness review, uses mixed scenarios rather than another isolated reading pass. Select an objective at random, explain the expected behavior, identify the evidence for failure, and state the corrective direction. Review errors by domain, then return to the source topic document for omissions. Schedule only when you can explain weak areas without relying on recalled answer patterns.
On the final review day, prepare administrative details from Cisco’s current pages, confirm that your registration reflects the intended exam, and avoid last-minute changes to study scope. A short review of call-flow diagrams and troubleshooting notes is more useful than beginning an unverified question collection.
How does CLACC fit a longer certification plan?
CLACC can be both a standalone specialist milestone and a concentration exam in the CCNP Collaboration path. Decide which outcome you need before scheduling: the specialist certification is earned by passing 300-815, while the CCNP Collaboration route also requires the applicable core exam combination described by Cisco.
If you already plan to take the core exam, map the overlap without assuming identical coverage. Core preparation may support general collaboration foundations, but CLACC requires focused work on advanced on-premises call control, gateways, border control, mobility, interoperability, supplemental features, and security. Keep separate checklists so familiarity with the core does not hide concentration gaps.
If recertification is the objective, compare the exam route with Cisco’s current recertification options. Cisco states that 300-815 can be used toward recertification, and Cisco’s CLACCM training page states that the training provides 40 Continuing Education credits toward recertification. These are planning inputs, not a complete statement of every recertification rule.
The broader update context also matters for candidates deciding between specialties. Cisco announced a 50/50 split between cloud and on-premises collaboration content beginning February 3, 2026. CLACC’s title and v2.0 topic list make its on-premises emphasis clear. Choose it when that emphasis matches the systems you expect to implement or support.
What should you do before registering?
Before registration, verify four things: the exam version, the certification outcome, your weak blueprint domains, and the current Cisco scheduling details. This short check prevents the most expensive preparation error—committing to an exam whose scope or timing does not match your plan.
Use the official v2.0 topic PDF to create a coverage checklist. Compare it with your lab notes and mark the objectives for which you have only recognition-level knowledge. Give those objectives a concrete action: draw a call flow, build a controlled scenario, analyze a fault, or explain the relevant security or interoperability dependency.
Confirm the administrative facts on Cisco’s exam page. The supplied official information lists English as the available exam language, a 90-minute duration, and a US$300 price with Cisco Learning Credits accepted. Cisco also states pass/fail grading, online results within 48 hours, and recertification use. Recheck the page because these are registration-sensitive details.
Finally, choose a test date only after your readiness review exposes no major untested domain. If your preparation relies mainly on answer memorization, postpone and return to the official topics and implementation reasoning. A sound next action is to document one complete call-flow diagnosis, then use that document to identify the next lab gap.
Conclusion
300-815 CLACC v2.0 rewards disciplined preparation around call paths, implementation dependencies, and evidence-based troubleshooting. Confirm the current version first, use the official topic document as the boundary of study, give the largest named domains proportional lab attention, and retain coverage for every remaining objective. Then verify Cisco’s current registration details and schedule only when you can explain not just what configuration should work, but why a failed call, route, media path, recording function, or trust relationship behaves as it does.
