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.

Constructor & Destructor Documentation

SIPTransaction::SIPTransaction	(	SIPEndPoint &	endpoint,
		OpalTransport &	transport,
		const PTimeInterval &	minRetryTime = PMaxTimeInterval,
		const PTimeInterval &	maxRetryTime = PMaxTimeInterval
	)

SIPTransaction::SIPTransaction	(	SIPConnection &	connection,
		OpalTransport &	transport,
		Methods	method = NumMethods
	)

Construct a transaction for requests in a dialog. The transport is used to determine the local address
