CLCOR ON Premises Call Control — 10 Questions

Question 1

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?

Accepted Answer

Configure the Inbound Calling Search Space on the SIP Trunk.. 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.

Answer

Assign a Device Pool that includes a dedicated MTP for every inbound call.

Answer

Set the 'Redirecting Number IE Delivery' to 'Off' for all ITSP trunks.

Question 2

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?

Accepted Answer

System > Location > Location Link. 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.

Answer

System > Region Information

Answer

Device > Device Settings > Location

Answer

System > Service Parameters > Bandwidth Manager

Question 3

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?

Accepted Answer

Max Audio Bit Rate. The 'Region' configuration defines the 'Audio Codec' allowed between two regions in the 'Region Relationship' matrix.

Answer

Network Locale

Answer

Location Bandwidth

Answer

Codec Preference List

Answer

Device Pool Assignment

Question 4

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

Accepted Answer

Another Media Resource Group. An MRGL is a list of MRGs. Therefore, you add MRGs to the list, and those MRGs contain media resources.

Answer

Conference Bridge

Answer

Region

Answer

Device Pool

Question 5

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

Accepted Answer

Standard Local Route Group. A Route List defines an ordered path. The items in that path are Route Groups, which have specific behaviors like 'sequential' or 'top-down' selection.

Answer

Partition

Answer

CSS

Question 6

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?

Accepted Answer

Configure a SIP Route Pattern for the domain portion of the URI.. To route incoming URI calls, the CUCM must be configured to accept the URI. This is done by checking the 'Accept Presence Subscription' or ensuring the SIP Trunk is associated with a Routing Lookup Policy that supports URI routing.

Answer

Add a translation pattern with a CSS that includes all partitions.

Answer

Disable the 'Redirect by Application' setting on the trunk.

Answer

Change the SIP Trunk protocol to H.323 for better URI handling.

Question 7

You have a cluster with two nodes. You need to verify the database replication status between the publisher and the subscriber. Which CLI command is the correct choice?

Accepted Answer

utils dbreplication runtimestate. The command 'utils diagnose test' or 'utils dbreplication runtimestate' is used to check the health of the database synchronization between nodes.

Answer

show status

Answer

utils network connectivity

Answer

show cluster status

Question 8

You are configuring a SIP trunk for a third-party gateway. The gateway requires the 'Diversion' header to be sent for call forwarding. Which setting on the SIP Profile enables this?

Accepted Answer

Diversion Header Delivery - Outbound. The 'Redirect by Application' or 'Diversion Header' settings in the SIP Profile determine how call forwarding info is passed to external gateways.

Answer

SIP Trunk Security Profile

Answer

Redirect by Application

Answer

Diversion Header Delivery - Inbound

Question 9

You are observing that calls are failing between two H.323 gateways. Which tool is best for verifying the H.225/H.245 signaling?

Accepted Answer

Real-Time Monitoring Tool (RTMT). The 'Cisco Unified Communications Manager Traces' viewed via RTMT are the primary way to debug H.323/SIP signaling messages.

Answer

Dialed Number Analyzer

Answer

Cisco Unified Reporting

Answer

Bulk Administration Tool

Question 10

When troubleshooting a failing call, which THREE items should be checked in the 'Route Pattern' configuration?

Accepted Answer

Numbering Plan type. Route pattern configuration impacts reachability, routing, and digit manipulation, making these the key areas for verification.

Answer

The phone's firmware version.

Answer

The Device Pool's date/time group.
