Refer to the exhibit. A collaboration engineer creates an allow list test file for a Mobile and Remote Access deployment. Which lines are needed to format the test in the file correctly?
What allows endpoints behind a NAT to discover the paths through which they will pass media?
Cisco media traversal technology has enabled a secure environment where internal video endpoints call and receive calls from external video endpoints. How does the Expressway-C and Expressway-E communicate?
Refer to the exhibit.
When configuring a search rule that routes calls to a zone, what occurs when 13358 is dialed?
An engineer configures a Cisco Collaboration environment to use Mobile and Remote Access for external access for company users. The engineer uses OAuth with refresh on the Cisco UCM SIP lines for extra security and improved user experience. During the setup, Mobile and Remote Access does not work, it is enabled on the Cisco UCM and Cisco Expressways. SIP trunks on ports 5090 and 5091 are configured to avoid conflicts with other SIP trunks between internal Cisco UCM clusters. The traversal zone also uses port 6500. The traversal zone between Expressways shows no errors, and the requests hit Expressway-E from the Internet. What is the reason that the solution does not work?
Refer to the exhibit. An engineer is deploying mobile and remote access in an environment that already had functioning Business to Business calling. Mobile and remote access SIP registrations are failing. To troubleshoot, SIP logs were collected. How is this issue resolved?
Refer to the exhibit.
Calls to locally registered endpoints are failing. At present, there are two endpoints
registered locally to this Expressway. An H.323 endpoint with an alias of “EndpointA” is registered, and a SIP endpoint with an alias of “EndpointB@pod1.local” is also registered. How is this issue resolved?
A collaboration engineer is configuring Cisco Webex Edge for video conferencing devices to provide support for Cisco Webex Control Hub configuration management. Which configuration control mode must be set on Cisco UCM for Control Hub to manage the on-premises device configuration?
An administrator configures a secure SIP trunk in Cisco UCM to Expressway-C. The SIP trunk fails to become active, and an examination of a packet capture finds that the TLS handshake failed with a “Certificate Unknown” error from Cisco UCM. To allow the Cisco UCM to trust the Expressway-C and establish a TLS connection, the administrator will upload the Expressway server certificate to the trust store. To which trust store must the certificate be uploaded?
When external video endpoints are called via a DNS zone, which dialing method requires DNS to be configured in the Expressway server?
