ON Premises Call Control practice questions

This domain covers on-premises call control in Cisco Unified CM: dial plan elements, route lists and route groups, partitions and calling search spaces, device and line configuration, softkey templates, call pickup, and device mobility. Questions present configuration scenarios and ask where to verify or change settings, or how to control call routing and registration behavior.

Courseiva uses original exam-style practice questions designed for learning and revision. The goal is to understand the concepts, recognise exam patterns, and improve through explanations — not memorise copied exam dumps.

What the exam tests

What to know about ON Premises Call Control

Be able to trace a call from dialed digits through translation patterns, route patterns, route lists, and route groups, and to locate where a feature like Transfer or Call Pickup is enabled. The key is knowing which configuration object actually controls the behavior being changed.

Route lists, route groups, and trunk selection order for outbound calls

Partitions, calling search spaces, and translation patterns for dial plan control

Softkey templates and device or line configuration for feature access

Device pools, regions, locations, and registration priority for endpoints

Watch out for

Common ON Premises Call Control exam traps

▸Confusing route group order inside a route list with route list order in a route pattern, which changes which provider is tried first.
▸Editing the phone's softkey template directly instead of checking the device pool or common device configuration that assigns it.
▸Assuming a calling search space on the phone grants access, when the line CSS and partition membership actually control dialing.

Redirecting number delivery is generally desired for call forwarding scenarios.

A
Assign a Device Pool that includes a dedicated MTP for every inbound call.
Why it fails: MTP is not strictly required for inbound routing unless specific signaling requirements exist.
B
Configure the Inbound Calling Search Space on the SIP Trunk.
The Inbound CSS is required to allow the trunk to reach the target directory number.
C
Set the 'Redirecting Number IE Delivery' to 'Off' for all ITSP trunks.
Why it fails: Redirecting number delivery is generally desired for call forwarding scenarios.
D
Configure the 'Significant Digits' field on the SIP Trunk to strip the carrier prefix.
Significant digits are used to match the incoming called number to the DNs in CUCM.
E
Create a SIP Trunk Security Profile with 'Accept Replaces Header' enabled.
This is often required for features like call transfers and parking coming from an ITSP.

ON Premises Call Control questions

A 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?

Which TWO configuration steps must be completed to ensure proper redundancy for a CUCM group? (Select TWO)

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?

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?

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?

An administrator is configuring a new SIP trunk between CUCM and a CUBE. To ensure that CUCM correctly handles mid-call signaling updates such as hold/resume, which parameter in the SIP Profile should be verified?

You are troubleshooting a one-way audio issue on calls routed through a specific region. Which setting in the Region configuration specifically controls the codec used between two locations?

Which component in CUCM is responsible for providing the necessary resources for conference calls, such as hardware or software-based conference bridges?

Which field in a Route Pattern determines how CUCM processes a call when a user dials a number that matches the pattern?

How do you verify if a phone is registered to the primary CUCM subscriber?

Which protocol is primarily used by CUCM to communicate with endpoints for registration and call control?

What is the result of using a '#' character at the end of a Route Pattern?

Which service, when enabled, allows CUCM to act as a recording server for calls?

You are implementing a SIP trunk to the PSTN. The carrier requires the 'Diversion' header for call forwarding scenarios. Where in CUCM do you configure this?

Which TWO of the following are valid components of an MRGL (Media Resource Group List)?

Which THREE of the following are valid states that can be configured in a Route List?

Which THREE of the following items are considered part of the 'Cisco Unified Communications Manager' infrastructure redundancy model?

You want to ensure that a specific device pool always uses a G.729 codec for inter-site calls. What is the most effective approach?

You are configuring a URI-based dial plan in CUCM 14. You have successfully enabled 'Allow Proxying of Requests' on the SIP Trunk Security Profile. What is the next mandatory configuration step to ensure the CUCM can correctly route incoming calls based on the Request-URI?

Which CUCM feature allows an administrator to automatically register new phones using a pre-defined device template?
