Refer to the exhibits.
Regions have been configured for all major branches based on the available circuit bandwidth. Some calls from Region A endpoints to Region B endpoints are failing to connect. How is this issue resolved?
An organization needs to ensure that the Cisco UCM can provide a resume softkey to users on their desk phones when they disconnect an anchored call on their mobile phone. Which solution must be used to accomplish these goals?
What are the elements for Device Mobility configuration?
A customer must advertise some numbers through GDPR on Call Manager. The Cisco UCM already is advertising some URIs to other clusters with GDPR, but the customer wants to ensure that specific numbers are advertised. Where under the Cisco UCM Admin page > Call Routing > Global Dial Plan Replication must that set of numbers be configured?
Which two extended capabilities must be configured on dial peers for fast start-to-early media scenarios
(H.323 to SIP interworking)? (Choose two.)
A customer reports that outbound calls from Cisco UCM to Cisco Unified Border Element are not getting early media. During troubleshooting, the customer finds that Cisco UCM is sending a delayed offer SIP INVITE. Cisco Unified Border Element responds with a 183 Session Progress with SDP message. However, the customer finds that Cisco UCM does not respond to the 183 messages. Which action must the customer perform to resolve the problem?
A Collaboration engineer wants to deploy Global Dial Plan Replication for advertising its global dial plan data, including the global dial plan data that was configured locally and any data that was learned from other clusters. The engineer is configuring the inter-cluster lookup service on the Cisco UCM and activated the ILS service and configured the cluster IDs.
What is the next step in the configuration?
When configuring hunt groups, where does the administrator add the individual directory numbers that should be part of the group?
An administrator manages an environment with mobile users who commonly move between locations and take IP phones to remote sites. When mobile users are at one of the sites, users report issues with call quality, such as the audio cutting in and out. In addition, the affected area has a low bandwidth connection compared to other sites, so the administrator has put these devices in a region with an inter-region restriction of 8 kbps per call. Which feature must the administrator configure to mitigate the issue?
Some Cisco mobility users cannot resume calls on the desk phone after they hang up on a mobile phone. The users have Cisco IP phones registered to the Cisco UCM. Which set of configuration steps resolve the issue?
Refer to the exhibit.
The Cisco Unified Border Element receives an INVITE matching inbound dial peer 5002. The outbound dial peer supports only iLBC. and a Local Transcoding Interface is allocated. Based on the configuration and SDP from the INVITE message, which codec is chosen by Cisco Unified Border Element for the inbound call leg?
After configuring a Cisco CallManager Express with Cisco Unity Express, inbound calls from the PSTN SIP trunk receive a ring tone for 20 seconds and then a busy signal instead of voicemail. Which configuration fixes this problem?
What is the relationship between partition, time schedule, and time period in Time-of-Day routing in Cisco Unified Communications Manager?
A user requests a feature to send an active call to the mobile phone number on the physical phone. As an administrator, what should be configured in the Cisco UCM to accomplish this?
A company was looking at the IT charges and saw many long-distance and international calls primarily to sites in North America and around the world. The administrator wants to optimize the PSTN expense. Which dial plan configuration reduces PSTN connectivity charges by using the IP network to bring the egress point to the PSTN as close as possible to the called number?
An engineer configured extension mobility to allow users to roam between phones while taking their numbers and specific device settings with them. Users are now getting "Error:- XML Error [4| Parse Error" on their phones. Which action will resolve this issue?
Which action is correct with respect to toll fraud prevention configuration in the Cisco Unified Communications Manager Express?
What does VoIP trace in a Cisco Unified Border Element do?
Refer to the exhibit.
ILS has been configured between two hubs using this configuration. The hubs appear to register successfully, but ILS is not functioning as expected. Which configuration step is missing?
An administrator discovers that employees are making unauthorized long-distance and international calls from logged-off Extension Mobility phones when the authorized users are away from their desks Which two configurations should the administrator configure in the Cisco UCM to avoid this issue? (Choose two.)
