NEW QUESTION # 202
A company has a Cisco Collaboration Solution with a Cisco UCM for internal and external voice services and Cisco Expressways for video endpoint registration and B2B communications. How can an engineer block B2B traffic from getting to the Cisco UCM and still allow video endpoints to call externally on voice?
Answer: B
Explanation:
Blocking calls based on the call source allows precise control over where traffic is allowed to go.
By blocking any calls originating from the B2B traversal zone toward Cisco UCM, the engineer prevents B2B traffic from reaching UCM while still allowing internal video endpoints to route external voice calls through the appropriate zones and search rules. This preserves external calling functionality without exposing Cisco UCM to B2B traffic.
