Constructor & Destructor Documentation

H323_RTP_UDP()

H323_RTP_UDP::H323_RTP_UDP	(	const H323Connection &	connection,
		RTP_UDP &	rtp
	)

rtp	RTP session

Member Function Documentation

ExtractTransport()

virtual PBoolean H323_RTP_UDP::ExtractTransport ( const H245_TransportAddress &  pdu, PBoolean  isDataPort, unsigned &  errorCode  )

protectedvirtual

OnReceivedAckPDU()

virtual PBoolean H323_RTP_UDP::OnReceivedAckPDU ( H323_RTPChannel &  channel, const H245_H2250LogicalChannelAckParameters &  param  )

virtual

This is called after a request to create a channel occurs from the local machine via the H245LogicalChannelDict::Open() function, and the request has been acknowledged by the remote endpoint.

The default behaviour sets the remote ports to send UDP packets to.

Parameters

channel	Channel using this session.
param	Acknowledgement PDU

Implements H323_RTP_Session.

OnReceivedPDU()

virtual PBoolean H323_RTP_UDP::OnReceivedPDU ( H323_RTPChannel &  channel, const H245_H2250LogicalChannelParameters &  param, unsigned &  errorCode  )

virtual

This is called after a request to create a channel occurs from the local machine via the H245LogicalChannelDict::Open() function, and the request has been acknowledged by the remote endpoint.

The default behaviour sets the remote ports to send UDP packets to.

Parameters

channel	Channel using this session.
param	Acknowledgement PDU
errorCode	Error on failure

Implements H323_RTP_Session.

OnSendingAckPDU()

virtual void H323_RTP_UDP::OnSendingAckPDU ( const H323_RTPChannel &  channel, H245_H2250LogicalChannelAckParameters &  param  ) const

virtual

This is called when request to create a channel is received from a remote machine and is about to be acknowledged.

Parameters

channel	Channel using this session.
param	Acknowledgement PDU

Implements H323_RTP_Session.

OnSendingPDU()

virtual PBoolean H323_RTP_UDP::OnSendingPDU ( const H323_RTPChannel &  channel, H245_H2250LogicalChannelParameters &  param  ) const

virtual

Fill out the OpenLogicalChannel PDU for the particular channel type.

Parameters

channel	Channel using this session.
param	Open PDU to send.

Implements H323_RTP_Session.

OnSendRasInfo()

virtual void H323_RTP_UDP::OnSendRasInfo ( H225_RTPSession &  info )

virtual

This is called when a gatekeeper wants to get status information from the endpoint.

The default behaviour calls the ancestor functon and then fills in the transport fields.

Parameters

info	RTP session info PDU

Implements H323_RTP_Session.
