An administrator is asked to configure egress call routing by applying globalization and localization on Cisco UCM. How should this be accomplished?

A.

Localize the calling and called numbers to PSTN format and globalize the calling and called numbers in the gateway.

B.

Globalize the calling and called numbers to PSTN format and localize the calling number in the gateway.

C.

Localize the calling and called numbers to E. 164 format and globalize the called number in the gateway.

D.

Globalize the calling and called numbers to E. 164 format and localize the called number in the gateway.

An administrator is configuring a cluster for ILS and wants to limit the amount of entities that Cisco Unified Communications Manager can write to the database for data that is learned through ILS. Which service parameter is used to adjust this limit?

A.

ILS Max Number of Learned Objects in Database

B.

ILS Active Learned Object Upper Limit

C.

Global Data Service Parameter Limit

D.

Imported Dial Plan Replication Database Object Lower Limit

Refer to the exhibit. A collaboration engineer is troubleshooting an issue where the PSTN calls of a Cisco UCM IP phone user are not reaching the PSTN gateway. Which action resolves the issue?

A.

Change the calling search space of the user's line or device.

B.

Change the "Call Classification" to "OnNet" on the route pattern.

C.

Ensure that the user's phone is assigned to a device pool with the correct local route settings.

D.

Deselect "Block this pattern" on the route pattern.

Refer to the exhibit. An administrator configured a new SIP trunk between Cisco UCM and Cisco Unified Border Element. Calls that use this new trunk are failing, and debugs from the Cisco Unified Border Element do not show any signaling received from Cisco UCM. The administrator verified that OPTIONS is enabled on the SIP profile configured on the trunk on Cisco UCM. The route pattern matched for this call is correctly configured to send calls to the Cisco Unified Border Element using this new trunk. What is the cause of this failure?

A.

The calling search space on the calling line/device does not contain the partition of the route pattern

B.

The called party number is not complete because it contains only 7 digits

C.

A connectivity issue between Cisco UCM and Cisco Unified Border Element prevents Cisco UCM from receiving a response to the OPTIONS it is sending to Cisco Unified Border Element

D.

There are multiple matches for the dialed number, and Cisco UCM is trying to send the call to SEP2834A2824611 rather than Cisco Unified Border Element

Refer to the exhibit.

An administrator has configured a SIP trunk between two Cisco UCM clusters. For calls that should use the trunk, the calls fail with a fast busy. The administrator checks the Cisco CallManager SDL traces and found that the cluster to which the calling device is registered never sends an INVITE to the destination cluster. The administrator also verifies that all nodes from both clusters are powered on, and the CallManager service is running. How is this issue resolved?

A.

The administrator needs to disable OPTIONS pings on the SIP trunks for both clusters.

B.

The administrator must allow connectivity so that TCP connections do not fail between the nodes.

C.

The administrator needs to enable OPTIONS pings on the SIP trunks for both clusters.

D.

The administrator must associate the route pattern with a calling search space the device can dial.

Refer to the exhibit. A standard local route group is configured for long-distance calls. Calls from building A succeed, but calls from building B fail. On the system. Each building has is own device pool. The DNA tool is used to test the configuration. How is this issue resolved?

A.

Change the partition of the route pattern

B.

Add a sip trunk inside route group Standard Local Route Group.

C.

Modify the route pattern to add a prefix of 91

D.

Add a local route group on the device pool configuration.

An administrator is configuring an Intercluster Lookup Service between 10 Cisco UCM clusters. Due to security requirements, certificate-based authentication must be used. Due to the deployment size, the administrator wants to avoid manually exchanging certificates between the clusters. Which two steps must be followed to meet these requirements? (Choose two)

A.

Set all dusters to standalone on the ILS configuration page.

B.

Install multiserver CA-signed Tomcat certificates on all cluster publishers.

C.

Enable password-based authentication in conjunction with certificate-based authentication.

D.

Ensure that the cluster ID for all clusters is the same.

E.

Install multiserver CA-signed CallManager certificates on all cluster publishers.

An administrator is working on an issue between the customer s Cisco Unified Border Element and the service provider. The provider only wants to see mid-call signaling from the Cisco Unified Border Element for fax calls. Which command must be configured on Cisco Unified Border Element?

A.

midcall-signallng passthru

B.

midcall-signaling preserve-codec

C.

no update-callerid

D.

midcall-signaling passthru media-change

An administrator is troubleshooting call failures on an H.323 gateway via the CLI. To see signaling for media and call setup, which debug must the Administrator turn on?

A.

debug H.323 messages

B.

debug H.225 asn1

C.

debug H.246 asn 1

D.

debug H.225 media

E.

debug H.323 asn 1

An engineer set up and successfully tested a TEHO solution on the Cisco UCM. PSTN calls are routed correctly using the IP WAN as close to the final PSTN destination as possible. However, suddenly, calls start using the backup local gateway instead. What is causing the issue?

A.

WAN connectivity

B.

LAN connectivity

C.

route pattern

D.

route list and route group
