Ip address trusted list - B . voice service volp

An engineer has two cisco UCM Clusters and wants to integrate them using ILS with TLS certificates. Cluster A (pub and 1 subscriber) will be the hub, and Cluster B (pub and 1 subscriber) will be the spoke. Both Clusters have self-signed certificates. The engineer has exchanged Publisher A and subscriber B Tomcat certificates, but the connection fails.
What is the cause of the failure?
- A . The password is incorrect.
- B . Cluster IDs are not unique.
- C . The tomcat certificate from Cluster B must be the publisher.
- D . The engineer needs to exchange the CallManager certificate.
Refer to the exhibit.
While troubleshooting call failures on the Cisco Unified Border Element, an administrator notices that messages are being sent to the service provider, but there is no response The administrator later learns that this SIP provider does not support PRACK.
Which header should be removed from the SIP message to resolve this issue?
- A . Content-Disposition: session:handling=required
- B . Require 100rel
- C . Contact <sip: [email protected]:5060>

The company Cisco UCM cluster has two different gateways for off-net calls. The current configuration uses 9 as a prefix to get to the main gateway. The secondary gateway is for any calls that start with 9713, but this is not yet configured. The admin does not want to add more route patterns other than the current 9 prefix for the gateway to the Cisco UCM.
How must the Cisco UCM be configured to meet the requirements?
- A . Configure two CSSs. then add a translation pattern with the secondary CSS to send calls with 9713 to the secondary gateway.
- B . Configure two partitions and two CSSs, then add a translation pattern with the secondary CSS to send all calls with 9713 to the secondary gateway.
- C . Create a Standard Route Group to dynamically route calls with prefix 9713 to the secondary gateway.
- D . Configure a Route Group and a Route List to send calls with prefix 9713 to the secondary gateway.
An administrator is configuring an Intercluster Lookup Service between 10 Cisco UCM clusters. Due to security requirements, certificate-based authentication must be used. Due to the deployment size, the administrator wants to avoid manually exchanging certificates between the clusters.
Which two steps must be followed to meet these requirements? (Choose two)
- A . Set all dusters to standalone on the ILS configuration page.
- B . Install multiserver CA-signed Tomcat certificates on all cluster publishers.
- C . Enable password-based authentication in conjunction with certificate-based authentication.
- D . Ensure that the cluster ID for all clusters is the same.
- E . Install multiserver CA-signed CallManager certificates on all cluster publishers.
A company is using Cisco Jabber on-premises to make B2B calls on video. The calls are using Cisco Expressway-C and Expressway-E and have been configured in Cisco UCM to be able to call any URI on the internet. The Jabber client also has voice enabled and must be able to call local, regional, and international numbers.
Where must Cisco UCM be configured to meet this requirement for URI dialing?
- A . Enter "!#" in the route pattern section tied to a route group and list.
- B . Enter "*" in the SIP route pattern.
- C . Enter "!#" in the SIP route pattern.
- D . Enter ".*" in the route pattern section tied to a route group and list.

Alter a new SIP trunk is configured from a third-party SIP trunk provider, the call does not seem to work. A troubles hooting tool and a tiace log from the Cisco Unified Border Element shows that there is communication with the provider and that it is sending out SDP information in the 2XX response.
Why is the call not working?
- A . The Cisco Unified Border Element does not have any PDVM resources to terminate the SIP trunk assigned.
- B . The SIP provider expects a delayed offer.
- C . The SIP provider expects an early offer.
- D . The Cisco Unified Border Element must be licensed for third-party SIP trunks.
