Parameters
connectionConnection to endpoint for channel
capabilityCapability channel is using
directionDirection of channel

Member Function Documentation

RTP_DataFrame::PayloadTypes H323_RealTimeChannel::GetDynamicRTPPayloadType ( ) const
virtual PBoolean H323_RealTimeChannel::OnReceivedAckPDU ( const H245_OpenLogicalChannelAck &  pdu)
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 makes sure the parameters are compatible and passes on the PDU to the rtp session.

Parameters
pduAcknowledgement PDU

Reimplemented from H323Channel.

virtual PBoolean H323_RealTimeChannel::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 in H323_ExternalRTPChannel, and H323_RTPChannel.

virtual PBoolean H323_RealTimeChannel::OnReceivedPDU ( const H245_OpenLogicalChannel &  pdu,
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 makes sure the parameters are compatible and passes on the PDU to the rtp session.

Parameters
pduOpen PDU
errorCodeError code on failure

Reimplemented from H323Channel.

virtual PBoolean H323_RealTimeChannel::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 in H323_ExternalRTPChannel, and H323_RTPChannel.

virtual PBoolean H323_RealTimeChannel::OnSendingPDU ( H245_OpenLogicalChannel &  openPDU) const
virtual

Fill out the OpenLogicalChannel PDU for the particular channel type.

Parameters
openPDUOpen PDU to send.

Implements H323Channel.

virtual PBoolean H323_RealTimeChannel::OnSendingPDU ( H245_H2250LogicalChannelParameters &  param) const
virtual

Fill out the OpenLogicalChannel PDU for the particular channel type.

Parameters
paramOpen PDU to send.

Reimplemented in H323_ExternalRTPChannel, and H323_RTPChannel.

virtual void H323_RealTimeChannel::OnSendOpenAck ( const H245_OpenLogicalChannel &  open,
H245_OpenLogicalChannelAck &  ack 
) const
virtual

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

Parameters
openOpen PDU
ackAcknowledgement PDU

Reimplemented from H323Channel.

virtual void H323_RealTimeChannel::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 in H323_ExternalRTPChannel, and H323_RTPChannel.
