Member Function Documentation

virtual unsigned H323_RTPChannel::GetSessionID ( ) const [virtual]

Indicate the session number of the channel. Return session for channel. This returns the session ID of the RTP_Session member variable.

Reimplemented from H323Channel.

virtual BOOL H323_RTPChannel::OnSendingPDU ( H245_H2250LogicalChannelParameters & param ) const [virtual]

Fill out the OpenLogicalChannel PDU for the particular channel type.

Parameters:

param

Open PDU to send.

Implements H323_RealTimeChannel.

virtual void H323_RTPChannel::OnSendOpenAck ( 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:

param

Acknowledgement PDU

Implements H323_RealTimeChannel.

virtual BOOL H323_RTPChannel::OnReceivedPDU	(	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:

param	Acknowledgement PDU
errorCode	Error on failure

Implements H323_RealTimeChannel.

virtual BOOL H323_RTPChannel::OnReceivedAckPDU ( 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:

param

Acknowledgement PDU

Implements H323_RealTimeChannel.
