A user takes an IP phone from one office to another and just called you to inform that the phone does not work in the new location. Which three things should you check to resolve the issue? (Choose three)
Make sure that the device mobility information contains the correct IP subnet information.
Make sure that the physical locations are properly assigned under device pools.
Recreate the phone under a new cluster.
Make sure that the device pool is assigned to a device mobility group.
Reconfigure the remote destination profile.
Check whether the phone is registered under a different MAC address.
Check the local DHCP information for possible clues.
After an IP Phone gets IP address information from DHCP, what is the next step in the initialization process?
CTL and ITL files are downloaded.
The phone requests its VLAN information.
The DHCP offer is sent from the phone
The TFTP server is contacted for configuration information.
Nothing else is required, the phone is operational at this stage
Which configuration can be dynamically set using the Cisco Unified Communications Manager Device Mobility feature?
phone model and protocol
SRST reference and directory number
CSS and local gateway
partition and CSS
media resources and permanent bridges
Which two issues can prevent an IP Phone from receiving an IP address via DHCP? (Choose two.)
The DHCP server is not on the same VLAN as the phone.
The DHCP scope's leases are exhausted.
DHCP Option 150 is incorrect.
The TFTP server is not reachable.
The DHCP scope is not defined for the subnet of the phone.
Which two troubleshooting tools would initially be the best to use when troubleshooting the PSTN gateway side of a call routing issue while using Cisco Unified Communications Manager? (Choose two.)
RTMT trace output
Cisco IOS debug commands
Dialed Number Analyzer output
Cisco Unified Communications Manager alerts
Cisco IOS show commands
Refer to topology and Exhibits below:
From the perspective of the Cisco Unified Communications Manager, what is the status of the MGCP gateway?
Which Cisco Unified Communications Manager troubleshooting tool can be used to determine the digit manipulation path a call takes within the Cisco Unified Communications Manager system from the perspective of a specific directory number, without having the actual device at hand?
Cisco Unified Communications Manager Serviceability
Cisco Unified Communications Manager Dialed Number Analyzer
Cisco Unified Communications Manager Real Time Monitoring Tool
Cisco Unified Syslog Viewer
Cisco IOS debugs
Which set is likely to resolve an issue with one-way audio on an H.323 gateway? A)
What does the debug output show? Refer to the exhibit.
a DSP farm profile shutdown
a DSP farm profile registration failure due to a TCP connection error
a DSP farm profile registration failure Message due to a mismatched name
that SCCP is not activated
When the command utils dbreplication status is executed on the Cisco Unified Communications Manager CLI, which step should be taken next to check the database replication status?
View the activelog file.
Run the same command on all nodes of the cluster.
Restart the Cisco CallManager service.
The command utils dbreplication runtimestate must be run on the publisher.
The command utils dbreplication runtimestate must be run on the subscriber.
During a conference that is hosted on a Cisco TelePresence Server, which three circumstances determine that some participants do not have video, but they do have audio? (Choose three.)
The participants have no video component.
No free screen licensing ports are available.
No video ports are available in a slave Cisco TelePresence Server configuration.
The maximum number of participants is exceeded.
In all Cisco TelePresence deployments, some participants are connected only via audio.
No video ports are available in a single Cisco TelePresence Server configuration.
When you troubleshoot call connection problems in an H.323 gateway, which command allows you to verify the allocation of DSPs?
debug voip dialpeer
debug voip h324
debug voip ccapi inout
debug vtsp session
debug voip tsp
John Johnson is trying to leach Jane Smith at net Cisco Untied IP phone by dialing net directory URI, but the call fails. What are two possible reasons for the call failure? (Choose two) Refer to the exhibit.
The CSS that is used by John's Cisco Jabber device does not contain the partition to teach Jane's endpoint.
The dialed directory URI and the provisioned directory URI do not match.
Cisco Unified Communications Manager is blocking the call.
Cisco Unified Communions Manager matched the host portion of Jane's URI to a SIP trunk and fouled the call to another cluster.
The directory URI should not be entered under the user configuration page Instead, the directory URI should be entered directly into Jane’s line configuration page.
Jane's endpoint does not support blended addressing.
Which Cisco TelePresence Management Suite feature provides proactive suggestions for resolving error conditions and also provides a centralized view of all statuses and configuration errors for managed devices?
Cisco WebEx in Cisco TelePresence Management Suite
Cisco TelePresence scheduling
Refer to the exhibit.
Local 10-digit dialing in the North American Numbering Plan to area code 456 is failing. Which two changes are needed to enable 10-digit dialing? (Choose two.)
Change dial peer 210 to destination-pattern 456.......
Change dial peer 210 to destination-pattern 9456.......
Change dial peer 210 to port 0/0/0:23.
Remove the command prefix 456 from dial peer 210.
A user is trying to call a mobile phone using the number 547895341, where 5 is the prefix to can off-net numbers. Calls to mobile phones have worked in past, but now the call does
not work. Which three areas should you check, to resolve the issue? (Choose three)
Verify that the Cisco Unified Border Element is running.
Verify the search pattern.
Verity the route pattern, route list, and route group.
Check that Cisco VCS Control and Cisco VCS Express are getting through the firewall.
Verify that me PSTN line is connected to the cisco Unified Communications Manager.
Verify that the connection to and from the Cisco Unified Border Element is good.
Refer to the exhibit, which displays the output of the debug ccsip messages command on a Cisco router.
What is the negotiated dual tone multifrequency on this call?
When a database replication issue is suspected, which three tools can be used to check the database replication status? (Choose three.)
Cisco Unified Communications Manager RTMT tool
Cisco Unified Communications Manager Serviceability interface
Cisco Unified Reporting
Cisco Unified Communications Manager CLI interface
Cisco IP Phone Device Stats from the Settings button
