Can I specify a timeout period for a Cisco Unified IP Phone, so that the phone times out after a period of inactivity?
A. Yes, you can specify whether an IP phone times out after a configured period of inactivity, forcing the user to log in again, by changing the value in the Cisco Unified IP Phone Timeout Period setting in the Administration > Options window.
