Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 21

When a phone is registered over Mobile and Remote Access, where does it register?

Answer options

• A. Cisco Unified Presence Server
• B. Expressway-E
• C. Cisco Unified Communications Manager
• D. Expressway-C

Correct answer: C

Explanation

The correct answer is C, Cisco Unified Communications Manager, as this is the primary component responsible for handling call control and registration for phones. The other options, while related to the system, serve different roles; for instance, Expressway-E and Expressway-C facilitate remote access but do not handle the registration directly.
