Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 188

A voice administrator enabled secure media between multiple Cisco UCM clusters that are connected via a SIP trunk. Which configuration parameter in the SIP trunk must be enabled to allow encrypted media traffic to traverse the SIP trunk?

Answer options

• A. Check the Allow iX Application Media check box in the SIP Profile.
• B. Check the SRTP Allowed check box in the SIP Trunk configuration.
• C. Check the RTP Allowed check box in the SIP Trunk configuration.
• D. Uncheck the RTP Allowed check box in the SIP Trunk configuration.

Correct answer: B

Explanation

The correct answer is B, as enabling the SRTP Allowed option is necessary for supporting secure media over the SIP trunk. Options A and C do not specifically address the requirement for encrypted media, while option D contradicts the need for RTP, which is essential for media transport.
