This post refers to the logout option of the IP phone.
1. When the logout button of the IP phone is disabled, the timeout interval is set to 120 seconds.
When the timeout interval is 120 seconds, the authentication information is sent to the user and the login fails. After the network has connected, the IP phone does not trigger the re-login.
2. When the logout button is enabled, the phone starts the timer and does not set the timeout period. After the network has connected, the phone triggers the login.
