Examples of javax.sip.Timeout

javax.sip.Timeout
This class contains the enumerations that define whether a timeout has occured in the underlying implementation. The application gets informed on whether a retransmission or transaction timer has expired. There are two types of Timeout, namely:
- {@link Timeout#RETRANSMIT} - This type is used to alert an application thatthe underlying retransmit timer has expired so an application can resend the message specific to a transaction. This timer is defaulted to 500ms and is doubled each time it is fired until the transaction expires {@link Timeout#TRANSACTION}. The default retransmission value can be changed per transaction using {@link Transaction#setRetransmitTimer(int)}. The RETRANSMIT type is exposed to the following applications as follows:
  - User Agent - Retransmissions on Invite transactions are the responsibility of the application. This is due to the three way handshake for an INVITE Request. All other retransmissions are handled by the underlying implementation. Therefore the application will only receive this Timeout type specific to Invite transactions.
  - User Agent with No Retransmission - an application can configure an implementation to handle all retransmissions using property characteristics of the {@link SipStack}. Therefore a Timeout of this type will not be passed to the application. The application will only get notified when the {@link Timeout#TRANSACTION} occurs.
  - Stateful Proxy - a stateful proxy remembers transaction state about each incoming request and any requests it sends as a result of processing the incoming request. The underlying implementation will handle the retransmissions of all messages it sends and the application will not receive {@link Timeout#RETRANSMIT} events, however the application will get notified of {@link Timeout#TRANSACTION} events. As an Invite transaction is end to end a stateful proxy will not handle the retransmissions of messages on an Invite transaction, unless it decides to respond to the Invite transaction, in essence becoming an User Agent Server and as such should behave as described by the User Agent semantics above bearing in mind the retranmission property of the underlying implementation.
  - Stateless Proxy - as a stateless proxy acts as a simple forwarding agent, i.e. it simply forwards every message it receives upstream, it keeps no transaction state for messages. The implementation does not retransmit messages, therefore an application will not receive {@link Timeout#RETRANSMIT}events on a message handled statelessly. If retransmission semantics are required by an application using a stateless method, it is the responsibility of the application to provide this feature, not the underlying implementation.
- {@link Timeout#TRANSACTION} - This type is used to alert an application that the underlying transaction has expired. A transaction timeout typically occurs at a time 64*T1 were T1 is the initial value of the {@link Timeout#RETRANSMIT}, usually defaulted to 500ms. The TRANSACTION type is exposed to the following applications as follows:
  - User Agent - All retransmissions except retransmissions on Invite transactions are the responsibility of the underlying implementation, i.e. Invite transactions are the responsibility of the application. Therefore the application will only recieve TRANSACTION Timeout events on transactions that are not Invite transactions.
  - User Agent with No Retransmission - an application can configure an implementation to handle all retransmissions using property characteristics of the {@link SipStack}. Therefore a TRANSACTION Timeout will be fired to the application on any transaction that expires including an Invite transaction.
  - Stateful Proxy - a stateful proxy remembers transaction state about each incoming request and any requests it sends as a result of processing the incoming request. The underlying implementation handles the retransmissions of all messages it sends and will notify the application of {@link Timeout#TRANSACTION} events on any of its transactions. As an Invitetransaction is end to end a stateful proxy will not handle transaction timeouts on an Invite transaction, unless it decides to respond to the Invite transaction, in essence becoming an User Agent Server and as such should behave as described by the User Agent semantics above bearing in mind the retransmission property of the underlying implementation.
  - Stateless Proxy - as a stateless proxy acts as a simple forwarding agent, i.e. it simply forwards every message it receives upstream, it keeps no transaction state of the messages. The implementation does not maintain transaction state, therefore an application will not receive {@link Timeout#TRANSACTION} events on a message handled statelessly. If transaction timeout semantics are required by an application using a stateless method, it the responsibility of the application to provide this feature, not the underlying implementation.
