Detailed Description

Session Initiation Protocol transaction. A transaction is a stateful independent entity that provides services to a connection (Transaction User). Transactions are contained within connections. A client transaction handles sending a request and receiving its responses. A server transaction handles sending responses to a received request. In either case the SIP_PDU ancestor is the sent or received request.
