SipSessionAttributeListener

The TimerListener interface enables SIP servlet applications to handle timer events. Applications implementing this interface can receive notifications when a timer, set through the TimerService, expires. These notifications allow the application to perform specific actions or tasks at scheduled times.
To use this listener, the application must specify an implementation of the TimerListener interface in the listener element of the SIP deployment descriptor (sip.xml). Note that only one TimerListener can be defined per application.

Method:

timeout
void timeout(ServletTimer timer)
This method is called to notify the application that a specified timer has expired. The application can use this callback to perform tasks or actions scheduled for the timer’s expiration.
Parameters:
timer: The ServletTimer instance that has expired, providing details about the timer and its associated data.
