Member Function Documentation

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.

virtual PBoolean H323_RealTimeChannel::SetDynamicRTPPayloadType ( int  newType) [virtual]

Set the dynamic payload type used by this channel.

Parameters:
newTypeNew RTP payload type number
