Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 113

An administrator configures Cisco UCM to use UDP for SIP signaling and finds that an endpoint cannot make calls. Which action resolves this issue?

Answer options

• A. Change the common phone profile.
• B. Change the SIP dial rules.
• C. Change the SIP profile.
• D. Change the phone security profile.

Correct answer: D

Explanation

The correct answer is D because the phone security profile governs the security settings and protocols used by the endpoint, which can affect its ability to establish calls. Options A, B, and C may change various configurations, but they do not directly address the security settings that are crucial for SIP signaling to function properly.
