@SipListener

public @interface SipListener

The @SipListener annotation simplifies the process of defining listeners in a SIP application. Instead of declaring listeners in the deployment descriptor, you can use this annotation to specify a listener directly in the code. The type of the listener is automatically inferred from the interfaces implemented by the target class, making the configuration simple and less error-prone.
