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:

  pdu | Acknowledgement 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:

  param | Acknowledgement 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:

  pdu | Open PDU
  errorCode | Error 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:

  param | Acknowledgement PDU
  errorCode | Error 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:

  openPDU | Open 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:

  param | Open 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:

  open | Open PDU
  ack | Acknowledgement 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:

  param | Acknowledgement 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:

  newType | New RTP payload type number
