An administrator troubleshoots call failure in a new deployment and finds that the SIP INVITE messages sent to the service provider contain a diversion header with the user’s 4-digit directory number. These 4-digit directory numbers range from 1000 to 9999. The service provider is rejecting the calls because it requires that the diversion header contain 10 digits.
Which command on the Cisco Unified Border Element resolves this issue for all users?
A)

B)
![]()
C)

D)

- A . Option A
- B . Option B
- C . Option C
- D . Option D
Exhibit.

Refer to the exhibit. All calls from site A to site B are failing, and the issue has been identified as a media negotiation problem.
Which configuration change resolves the issue?
- A . Disable G.722 on all devices at both sites.
- B . Enable Early Offer on the SIP trunk.
- C . Increase the bandwidth allowance between the RTP_Reg and SJ_Reg regions to 64 kbps.
- D . Create a new audio codec preference list with G.711 U-law 64k as the highest priority and apply it to RTP_Reg and SJ_Reg.
A company has users that are logged in to hunt groups. However, there is a requirement for hunt group configurations to provide an option to turn on audible ringtones when calls to a line group arrive at a phone that is logged out and on a break. This ringtone alerts a logged-out user that there is an incoming call to a hunt list to which the line is a member, but the call does not ring at the phone of that line group member because of the logged-out status.
Which action meets this requirement?
- A . Configure the HLog softkey on the phone so that while a user is logged off, it plays an audible tone when a call is missed.
- B . Set the service parameter Party Entrance Tone to True."
- C . Configure the service parameter hunt group logoff notification and specify the name of the ringtone file.
- D . Set the service parameter Enterprise Feature Access number for hunt group logout and set up an access number
In Cisco Unified Communications Manager globalized call routing is implemented and must confirm that it is correctly implemented without making a call.
Which tool do you use for verification?
- A . Dialed Number Analyzer
- B . Real-Time Monitoring Tool
- C . SDI trace
- D . SDL trace
The administrator of ABC company is troubleshooting a one-way audio issue for a call that uses H.323 protocol (slow-start mode). The administrator requests that you provide the IP and port information of the Real- Time Transport Protocol traffic that had the one-way audio call.
You gather the H.225 and H.245 messages for one of the one-way audio calls.
Where can you find the RTP IP and port information for both sides? (Note: This call flow has not invoked any media resources like MTP or transcoders).
- A . H.245 Terminal Capability Set
- B . H.245 Open Logical Channel
- C . H.225 Connect
- D . H.245 Open Logical Channel Ack

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.
An engineer is configuring a Cisco UCM solution. The requirements state that some users in one location will receive calls from a number during work hours 09AM to 5PM, and another group will get the calls from the same number outside this defined timeslot. Users will also change the outgoing number when reaching out to customers based on the same time-of-day routing rules.
Which feature is needed to allow for this type of configuration?
- A . partitions
- B . route groups
- C . route lists
- D . CSS
Which two statements are correct with respect to the Client Matter Code setting in the route pattern configuration? (Choose two.)
- A . The Client Matter Code feature does not support overlap sending because the Cisco Unified CM cannot determine when to prompt the user for the code.
- B . If you check the Allow Overlap Sending check box, the Require Client Matter Code check box becomes disabled.
- C . If you check the Allow Overlap Sending check box, you can also check the Require Client Matter Code check box.
- D . The Client Matter Code feature does support overlap sending because the Cisco Unified Communications Manager can determine when to prompt the user for the code.
- E . The Client Matter Code has the option to configure Authorization Level such as in the Forced Authorization Code.

Refer to me exhibit.

A user cannot access Extension Mobility even after clicking the services button and selecting EM service. There is nowhere to place the username and password to sign In for this service.
What Is the cause of the issue?
- A . IP phone services Extension Mobility does not have the correct service URL configured.
- B . IP phone services Extension Mobility has XML Service Category configured.
- C . The Cisco IP phone has not checked the Extension Mobility checkbox.
- D . The Cisco IP phone is not subscribed to an Extension Mobility service.
An engineer needs to deploy the local route group feature to a Cisco UCM server by using the standard local route group. For each device pool, the engineer needs to specify a different PSTN access for emergency calls.
What must the engineer do?
- A . Add a new standard local route group. Select a route group as the new standard local route group in Device Pools. Create a route pattern of 911 that points to a route list that contains the new standard local route group.
- B . Create a new local route group name. In Device Pools, select a route group for that new local route group. Create a route pattern of 911 that points to a route list that contains the new local route group.
- C . Set a new local route group name. Select a route group as the new local route group in Device Pools. Create a route pattern of 911 that points to the new local route group.
- D . Add a new standard local route group. Select a route group as the new standard local route group in Device Pools. Create a route pattern of 911 that points to the new standard local route group.
