Constructor & Destructor Documentation

H323_RTPChannel::H323_RTPChannel ( H323Connection connection,
const H323Capability capability,
Directions  direction,
RTP_Session rtp 
)

Create a new channel.

Parameters:
connectionConnection to endpoint for channel
capabilityCapability channel is using
rtpDirection of channel RTP session for channel
H323_RTPChannel::~H323_RTPChannel ( )

Destroy the channel.


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 PBoolean 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:
paramAcknowledgement PDU

Reimplemented from H323_RealTimeChannel.

virtual PBoolean 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:
paramAcknowledgement PDU
errorCodeError on failure

Reimplemented from H323_RealTimeChannel.

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

Fill out the OpenLogicalChannel PDU for the particular channel type.

Parameters:
paramOpen PDU to send.

Reimplemented from 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:
paramAcknowledgement PDU

Reimplemented from H323_RealTimeChannel.

virtual bool H323_RTPChannel::SetSessionID ( unsigned  sessionID) [virtual]

Set the session number of the channel. During OLC negotations teh master may change the session number being used for the logical channel.

Returns false if the sesion could not be renumbered.

Parameters:
sessionIDNew session ID

Reimplemented from H323Channel.
