When the IP phone 2001 places a call to 9011 49403021 56001, the call is sent to the Cisco Unified Border Element as 40302156001 which is what the ITSP expects to receive. The ITSP support personnel claim that they never saw the call. Issuing the debug CCSIP message command on the Cisco Unified Border Element results in the message “SIP/2 0 404 Not Found”.

 

 

Refer to the Cisco Unified Border Element configuration, debug voice dial and ccsip messages exhibits. Which situation can cause this issued?

 

A.

The Cisco Unified Bolder Element is configured as an MGCP gateway also so that the call is attempted via the PSTN

B.

The command allow-connections sip to h323 is missing

C.

SIP error 404 means that a codec mismatch occurred Cisco Unified Communications Manager is sending the call as an early offer with G.711 codec.

D.

The Cisco Unified Communications Manager is rnisconfigured. The SIP invite should be sent to the ITSP at 10.1.2.1.2. The debug ccsip message shows the SIP invite being sent to 10.12.1.2.

 

Answer: B

Explanation: Explanation- As we can see in logs, the call is between two different signaling devices i.e. SIP and H.323 hence The command allow-connections sip to h323 is mandatory.

QUESTION 84  (Topic 2)

 

Your Cisco Unified CallManager 5.0 cluster has just started to use a third-party LDAP service. Users complain that they are unable to make changes to their passwords in their Cisco Unified CallManager user web pages. How should you resolve this problem?

 

A.

Restart the phones that are having problems to reinitialize the LDAP database.

B.

Have the users make changes to their passwords in the LDAP database.

C.

Configure automatic synchronization of the LDAP database.

D.

Change the passwords on the IP phone screen using the TUI.

 

Answer: B

 

 

QUESTION 85  (Topic 2)

 

Which two methods can be used to correct database replication issues in a cluster running Cisco Unified CallManager 4.1? (Choose two.)

 

< tr style="mso-yfti-irow: 0; mso-yfti-firstrow: yes">

A.

Enter the utils dbreplication repair command at the command-line prompt.

B.

Execute the dblhelper utility on the publisher.

C.

Use the SQL Server Enterprise Manager application to recreate the database subscription.

D.

Run the Cisco Unified CallManager BARS utility to restore the database to the subscriber.

E.

Use the Informix database utility to recreate the database subscription.

 

Answer: BC

 

 

QUESTION 86  (Topic 2)

 

You have configured the Enable Keep Alive check box under Trace Filter Settings. How does this change the trace output?

 

A.

It adds TCP socket numbers between the endpoint and Cisco Unified CallManager for the session.

B.

It maps the unique TCP handle for the endpoint to the MAC address of the endpoint in the trace output.

C.

It adds the IP address of the endpoint in hex.

D.

It adds the SCCP messages and all fields sent as part of that message.

 

Answer: D

Explanation:Enable Keep Alive Trace Activates trace for keepalive trace information in theCisco CallManager traces. Because each SCCP device reports keepalive messagesevery 30 seconds, and each keepalive message creates 3 lines of trace data.

 

 

QUESTION 87  (Topic
2)

 

You have received a trouble ticket stating that users in accounting are not able to use the CFwdAll softkey to forward their calls to voice mail. Their phones continue to ring when they receive inbound calls, even after they have pressed the CFwdAll softkey and the Messages button. What is a possible cause of this issue?

 

A.

The users have not been enabled to use CTI.

B.

The users have not been associated with their phones.

C.

The voice-mail ports are not registered.

D.

There is a database replication issue with the subscriber the phones are registered to.

E.

The phones are not configured to use the standard phone template.

 

Answer: D

Explanation: Symptom: IP Phones will not be able to set Call Forward All (CFA) and phones that are already CFA will be unable to clear the condition, even if the phone indicates that it is not forwarded.

Further Problem Description: Many times you will be able to tell when the problem first started by looking in the Application Event Viewer on all nodes for an Error message from CallManager. This message should state that an SDL connection to one or more nodes went OOS (out of service). Ideally the low level networking part of CallManager should alert all other processes when the SDL link goes down. This will allow them to reestablish their connections when the CallManager process recovers or is restarted. In this case they are n ever notified that the service went down, so they do not attempt to recover.

 

Conditions: After a stop or crash of the CallManager service on any node the connection between the processes that monitor thedatabasefor changes and the CallManager processes on all nodes will fail to re-establish. This results in the CFA changes being written to thedatabase(and can beseen in the CCMAdmin web page) but the CallManager process on each node will not be notified that the change occured.

 

 

 

Workaround: Restarting theDatabaseLayer Monitor service on all nodes in the cluster should recover the connection (this is not service impacting). In extreme cases a restart of CallManager may be necessary as well, which will be service impacting. Note that after the connection is restored the forwarding information internal to CM memory may be corrupted for phones that were “stuck” forwarded during the outage. To fix this change the CallingSearchSpace for CFA under the line that is “stuck”. Update the line, then reset the devices. You can then change the CFA CSS back to its original value and the phone should display the correct CFA information and calls should be routed appropriately.

 

 

QUESTION 88  (Topic 2)

 

Which three capabilities cannot be configured if the default dial peer is matched? (Choose three.)

 

A.

disable DID

B.

invoke a Tcl application

C.

enable dtmf-relay

D.

disable VAD

E.

set codec to G.711

F.

set preference to 1

 

Answer: BCD

Explanation: The Default Dial-Peer 0 peer_tag=0, pid:0

If no incoming dial peer is matched by the router or gateway, the inbound call leg is automatically routed to a default dial peer (POTS or Voice-Network). This default dial peer is referred to asdial-peer 0orpid:0.

Dial-peer 0(pid:0) has a default configuration that cannot be changed. The defaultdial-peer 0fails to negotiate non-default capabilities, services, and applications such as:

Non-default Voice-Network capabilities:dtmf-relay,no vad, and so forth.

Direct Inward Dial (DID)

QUESTION 89  (Topic 2)

 

You have received a trouble ticket stating that users are no longer hearing a second dial tone after pressing 9 to initiate an external call. The trouble ticket states that the second dial tone is played only after several additional digits are dialed. What is the mostly likely cause of this problem?

 

A.

The Cisco Unified CallManager server is experiencing CPU spikes, causing a delay in playing the second dial tone.

B.

A route pattern beginning with the digit “9” has been added to the route plan without the Provide Outside Dial Tone check box selected.

C.

A route pattern beginning with the digit “9” has been added to the route plan with the Call Classification parameter set to OnNet.

D.

The first gateway in the route group is not available, causing a delay in playing the second dial tone while Cisco Unified CallManager queries the
second gateway.

 

Answer: B

 

 

QUESTION 90  (Topic 2)

 

Cisco CallManager 5.0 has just been deployed in two locations across a wide-area link. A distributed model with an intercluster trunk has been used. When you call an IP phone at the remote site the phone rings, but as soon as the other person picks up the phone, the call is dropped.

 

Where should you look to diagnose the problem?

 

A.

locations

B.

system parameters

C.

media resource group

D.

Cisco Unified CallManager group

E.

Cisco Unified CallManager CTI traces
