Explanation

An IP or TCP reset in Cisco Unified Communications Manager drops and re-establishes the network connection for one specific IP phone without impacting any other registered devices.

Common mistakes.

B. A phone profile reset applies to all phones sharing the same common phone profile, making it a bulk action rather than a single-phone restart.
C. A region reset is not a phone restart operation - regions define codec selection and bandwidth constraints between groups of devices in CUCM.
D. A location reset is not a phone restart operation - locations are used for call admission control (CAC) to limit bandwidth consumption across WAN links.

Concept tested. Cisco CUCM single phone restart via IP/TCP reset
