Which feature allows users to log into different phones?

• A. Hot Desking
• B. Mobile Connect
• C. Extension Mobility
• D. Single Number Reach

Answer: (C)

Extension Mobility lets a user log into any supported IP phone, pulling in their own extension, preferences, and voicemail settings so the phone behaves as if it were their own. When they log in, the device loads their directory, speed dials, and call capabilities, allowing calls to be made and received on that phone with the user's identity. Logging out clears those user-specific settings, making the phone ready for the next person. This is exactly what enables moving between different phones in shared or hot-desking environments while keeping a consistent personal call identity. Other features might connect mobile devices or route calls to multiple devices, but they don’t provide the seamless login-to-different-phones capability that Extension Mobility offers.
