20+ practice questions focused on ON Premises Call Control — one of the most tested topics on the Cisco Implementing Cisco Collaboration Core Technologies (CLCOR, 350-801, v2.0 blueprint, CCNP Collaboration) (CLCOR) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start ON Premises Call Control PracticeA CUCM administrator is configuring a SIP trunk for a new ITSP. Which THREE actions must be performed to ensure proper inbound call routing from the provider?
Explanation: Inbound routing requires a SIP trunk, a properly configured Inbound CSS on the trunk, and a Translation Pattern or Route Pattern to match the incoming ANI/DNIS.
Which TWO configuration steps must be completed to ensure proper redundancy for a CUCM group? (Select TWO)
Explanation: Option D is correct because the CUCM group must be assigned to the Device Pool so that devices using that pool receive the ordered list of call-processing nodes for redundancy and failover. Option C is correct because the device itself must be assigned to that Device Pool, which is the mechanism that binds the device to the CUCM group and its redundancy configuration. Options A, B, and E are incorrect: separate SIP trunks per node are not required for CUCM group redundancy, partitions are used for dial-plan/calling-search-space scoping rather than node redundancy, and Heartbeat is a switch-level protocol unrelated to CUCM group failover.
An administrator needs to ensure that internal calls between two sites are routed over an MTP-required SIP trunk, but the calls are failing due to codec mismatch. Which CUCM service parameter setting should be verified to allow the MTP to be inserted?
Explanation: To allow MTP insertion for a SIP trunk that requires MTP, you must check the 'MTP Required' checkbox on the SIP trunk configuration and ensure the Media Resource Group List (MRGL) assigned to the trunk includes an MTP resource. This ensures that CUCM allocates an MTP for calls over that trunk when needed.
A user reports that calls to an external PSTN number are failing. The trace shows a '403 Forbidden' response from the provider. Where in CUCM should the administrator investigate the outbound calling search space (CSS) settings?
Explanation: When a user reports that calls to an external PSTN number are failing with a '403 Forbidden' response from the provider, the issue is often related to the outbound calling search space (CSS) configuration on the phone or device. The CSS determines which partitions a device can search for dialed numbers, and if the CSS does not include the partition containing the route pattern for the PSTN, the call will be blocked. The administrator should investigate the CSS settings on the phone, which is found under Device > Phone > CSS.
You are configuring a new location-based CAC policy in CUCM. You need to ensure that calls between two specific locations are restricted based on available bandwidth. Where must you configure the location relationship to define the audio bandwidth limit?
Explanation: In CUCM, the link between two locations must be defined under System > Location Bandwidth Manager > Link, specifying the bandwidth available for audio, video, and immersive video between the two specific locations.

Start with 10 questions to gauge your current understanding of ON Premises Call Control. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
ON Premises Call Control questions on the CLCOR frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
