Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 408

What makes Cisco Unified Border Element a better choice than a conventional Session Border Controller?

Answer options

• A. DTMF interworking
• B. SIP security
• C. Voice policy
• D. Address hiding

Correct answer: C

Explanation

Cisco Unified Border Element is superior due to its robust voice policy capabilities, allowing for more granular control over voice traffic. While DTMF interworking, SIP security, and address hiding are important features, they do not provide the same level of comprehensive management and customization for voice services as voice policy does.
