A.

Create one route group for each site and one global route list for PSTN calls that point to the local route group.

B.

Create a route group which has all the gateways and associate it to the device pool of every site.

C.

Create one global route list for PSTN calls that points to one global PSTN route group.

D.

Create a hunt group and assign it to each side route pattern

E.

Assign one route group as a local route group in the device pool of the corresponding site.

When locations-based Call Admission Control denies the call, which two masks can AAR apply when routing the call through the PSTN? (Choose two.)

A.

AAR destination mask

B.

called party transform mask

C.

external phone number mask

D.

+E.164 alternate number mask

E.

enterrise alternate number mask

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.

Cisco UCM has 100,000 entries in the database learned through the ILS Service.
Parameter ILS Max Number of Learned Objects in Database value is set to 100,000.
What will happen to learned data when the service parameter value is reduced to 50,000?

A.

Cisco UCM does not write additional ILS learned objects to the database and will delete the first 50,000 entries learned to keep it to the service parameter value.

B.

Cisco UCM does not write additional ILS learned objects to the database and will delete the last 50,000 entries learned to keep it to the service parameter value.

C.

Cisco UCM does not write additional ILS learned objects to the database and keeps the existing database entries.

D.

Cisco UCM will overwrite an entry for newly learned data and keep the parameter value at 100,000.

Refer to the exhibit.

The Cisco Unified Border Element receives an INVITE matching inbound dial peer 5002.

A.

G.711 A-law

B.

G.711 U-law

G.729br8

A customer is using a SIP trunk to route calls to ITSP to decrease the possibility of
downtime, the customer invested in a failover device How does the customer ensure reachability to ITSP, so that if one device on ITSP fails, the calls will be routed to another device?

Enable transmit security status on the SIP security profile

B.

Enable ANAT on the SIP profile.

C.

Monitor the link using network management toots, and if it fails, manually change the routing to another working device.

D.

Enable SIP Option Ping on the SIP profile.

B.

R2(config-ephone-dn)#park-slot timeout 60 limit 2 recall alternate 3002

R2(config-ephone-dn)#park reservation-group 1

D.

R2(config-ephone-dn)#park-slot timeout 30 limit 2 recall alternate 3002

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?

An engineer has two cisco UCM Clusters and wants to integrate them using ILS with TLS
certificates. Cluster A (pub and 1 subscriber) will be the hub, and Cluster B (pub and 1
subscriber) will be the spoke. Both Clusters have self-signed certificates. The engineer has
exchanged Publisher A and subscriber B Tomcat certificates, but the connection fails. What
is the cause of the failure?

A.

The password is incorrect.

B.

Cluster IDs are not unique.

C.

The tomcat certificate from Cluster B must be the publisher.

D.

The engineer needs to exchange the CallManager certificate
