Examples of javax.sip.Transaction

javax.sip.Transaction
Transactions are a fundamental component of SIP. A transaction is a request sent by a client transaction to a server transaction, along with all responses to that request sent from the server transaction back to the client transactions. User agents contain a transaction layer, as do stateful proxies. Stateless proxies do not contain a transaction layer. This specification provides the capabilities to allow either the SipProvider or SipListener to handle transactional functionality.
This interface represents a generic transaction interface defining the methods common between client and server transactions. @see TransactionState @author BEA Systems, NIST @version 1.2
