Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 76

Company X has a Cisco Unified Communications Manager cluster and a VCS Control server with video endpoints registered on both systems. Users find that video endpoints registered on Call manager can call each other and likewise for the endpoints registered on the VCS server. The administrator for Company X realizes he needs a SIP trunk between the two systems for any video endpoint to call any other video endpoint. Which two steps must the administrator take to add the SIP trunk? (Choose two.)

Answer options

• A. Set up a SIP trunk on Cisco UCM with the option Device-Trunk with destination address of the VCS server.
• B. Set up a subzone on Cisco UCM with the peer address to the VCS cluster.
• C. Set up a neighbor zone on the VCS server with the location of Cisco UCM using the menu option VCS Configuration > Zones > zone.
• D. Set up a SIP trunk on the VCS server with the destination address of the Cisco UCM and Transport set to TCP.
• E. Set up a traversal subzone on the VCS server to allow endpoints that are registered on Cisco UCM to communicate. AC

Correct answer:

Explanation

To enable communication between video endpoints on Cisco UCM and VCS, the administrator must set up a SIP trunk on both sides. Option A is correct because it establishes the trunk from Cisco UCM to VCS, while option D is also correct since it creates the reverse connection from VCS to Cisco UCM. The other options involve configurations that, while beneficial, do not directly establish the SIP trunk required for interoperability.
