(Choose two.)

Remove the long-distance & international pattern’s partitions from the calling search space of the physical phone.

Add the long-distance & international pattern’s partitions to the calling search space of the physical phone’s directory number.

Remove the long-distance & international pattern’s partitions from the calling search space of the device profile.

Add the long-distance & international pattern’s partitions to the calling search space of the physical phone.

Add the long-distance & international pattern’s partitions to the calling search space of the device profile

Q48. 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?

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.

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.

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

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

Q49. Refer to the exhibit.

Users report that outbound PSTN calls from phones registered to Cisco Unified Communications Manager are not completing. The local service provider in North America has a requirement to receive calls in 10-digit format. The Cisco Unified CM sends the calls to the Cisco Unified Border Element router in a globalized E.164 format. There is an outbound dial peer on Cisco Unified Border Element configured to send the calls to the provider. The dial peer has a voice translation profile applied in the correct direction but an incorrect voice translation rule applied, which is shown in the exhibit. Which rule modified DNIS in the format that the provider is expecting?

rule 1 /^/+([^1].*)/ /0111/

rule 1/^+1([2-9]..[2-9]……$)/ /1/

rule 1 /^([2-9]..[2-9]……$)/ /1/

rule 1 /^+1([2-9]..[2-9]……$)/ //

Q50. Calls to a particular extension are not routing to voicemail. The user reaches the voicemail system from the handset by pressing the Messages button Which configuration parameter causes this problem?

The voicemail pilot number for call forwarding is missing from the ephone-dn

The voicemail pilot number is missing from the call handling on Cisco Unity Express

The voicemail pilot number is missing from the telephony service configuration on Cisco UCME

The voicemail pilot number for call forwarding is missing from the ephone

Q51. Which two configuration parameters are prerequisites to set Native Call Queuing on Cisco Unified Communications Manager? (Choose two.)

Cisco IP Voice Media Streaming Service must be activated on at least one node in the cluster.

A unicast music on hold audio source must be configured.

Cisco RIS data collector service must be running on the same server as the Cisco CallManager service.

The maximum number of callers allowed in queue must be 10.

The phone button template must have the Queue Status Softkey configured.

Q52. Refer to the exhibit.

An engineer is troubleshooting a call-establishment problem between Cisco Unified Border Element and Cisco UCM. Which command set corrects the issue?

SIP binding in SIP configuration mode:
voice service voip sip
bind control source-interface GigabitEthernetO/0/0 bind media source-interface GigabitEthernetO/0/0

SIP binding In SIP configuration mode:
voice service volp
sip
bind control source-Interface GlgabltEthernetO/0/1 bind media source-Interface GlgabltEthernetO/0/1
