- B . Configure a neighbor zone on each server with a destination of the other Expressway-C.
- C . Configure a transform on each server to strip the port numbers at the end of the alias.
- D . Configure a transform on each server to convert the calling alias into the called alias.

An Expressway-E is configured using a single NIC with NAT.
How must the Expressway-C traversal client zone be configured to connect to the Expressway-E?
- A . TLS verify must be enabled.
- B . The zone pro le must be set to default.
- C . The peer address must be the Expressway-E NAT address.
- D . The peer address must be the Expressway-E LAN 1 IP address.
What is a description of an Interactive Connectivity Establishment?
- A . It is used by B2BUA to keep the firewall ports opened for inbound/outbound calls.
- B . It allows Mobile and Remote Access endpoints to connect video calls signaling peer-to-peer.
- C . It allows calling external endpoints with reduced overhead under VPN connections.
- D . It is used to find the best media path between network elements in traversal calls.
An engineer is deploying Mobile and Remote Access to allow external Cisco Jabber users to sign into a Cisco UCM cluster via Cisco Expressways. The users will sign-in in the format [email protected]. Contact photos for Jabber are hosted on a webserver with the FQDN of phonebook cisco.com.
Which configuration must be completed to allow external Jabber users to see contact photos?
- A . An HTTP allow list entry must be made on the Expressway-E for phonebook cisco.com.
- B . A SIP allow list entry must be made on the Expressway-E for .*@cisco.com.
- C . An HTTP allow list entry must be made on the Expressway-C for phonebook cisco.com.
- D . A SIP allow list entry must be made on the Expressway-C for .*@cisco.com.
Refer to the exhibit.
An administrator troubleshoots Cisco Jabber users experiencing issues when trying to log in and notices errors in the Jabber problem report log. The administrator also sees that the Intercluster Sync Agent service is not running on the IMM and Presence server.
Why is the Jabber client unable to sign in?
- A . The XmppSDK.dl le is missing from the IM and Presence server
- B . The XMPP stanza is not using the correct ID for the Jabber client.
- C . The XMPP bind failed on the IM and Presence server
- D . The Jabber client refused the XMPP bind connection.
A company is installing Cisco Collaboration infrastructure and one of the requirements is that they must be able to communicate with many external parties that are using H.323 and SIP. Internally they want to register the endpoints only on SIP.

- A . Interworking in Expressway-C
- B . Transcoding in Cisco Unified Communications Manager
- C . Transcoding in Expressway-C
- D . Interworking in Cisco Unified Communications Manager
