A
Assign a Device Pool that includes a dedicated MTP for every inbound call.
Why wrong: 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 wrong: 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?

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?

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 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?

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?

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?

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?

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

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

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?

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?

A user reports that their calls are failing when they roam to a different physical office site. You observe that the device is registered to the primary CUCM cluster but the Location-based CAC is blocking the call. What is the most likely cause?

You are troubleshooting a scenario where internal calls between two offices are using the G.711 codec, but you want them to use G.729 to save bandwidth. Where should you change the codec setting?

When designing a redundant CUCM deployment, which mechanism ensures that if a primary subscriber fails, phones automatically register to a secondary subscriber?

You need to prevent certain internal users from making international calls while allowing them to dial local numbers. What is the most efficient way to implement this in CUCM?

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

If a Translation Pattern is configured in CUCM, at what stage of the call processing does the digit manipulation occur?
