Directions | direction, | |||
OpalMediaSession & | session | |||
) |
Create a new channel.
connection | Connection to endpoint for channel |
capability | Capability channel is using |
direction | Direction of channel |
session | Session for channel |
H323_RTPChannel::~H323_RTPChannel | ( | ) |
Destroy the channel.

virtual PBoolean H323_RTPChannel::GetMediaTransportAddress | ( | OpalTransportAddress & | data, | |
OpalTransportAddress & | control | |||
) | const [virtual] |
Get the media transport address for the connection. This is primarily used to determine if media bypass is possible for the call between two connections.
The default behaviour returns false.
data | Data channel address |
control | Control channel address |
Reimplemented from H323Channel.
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 H323RTPSession member variable.
Reimplemented from H323Channel.
virtual PBoolean H323_RTPChannel::OnReceivedAckAltPDU | ( | const H245_ArrayOf_GenericInformation & | alternate | ) | [virtual] |
Alternate RTP port information for Same NAT
alternate | Alternate RTP ports |
Implements H323_RealTimeChannel.
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.
param | Acknowledgement 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.
param | Acknowledgement PDU |
errorCode | Error on failure |
Reimplemented from H323_RealTimeChannel.
virtual PBoolean H323_RTPChannel::OnSendingAltPDU | ( | H245_ArrayOf_GenericInformation & | alternate | ) | const [virtual] |
Alternate RTP port information for Same NAT
alternate | Alternate RTP ports |
Implements H323_RealTimeChannel.
virtual PBoolean H323_RTPChannel::OnSendingPDU | ( | H245_H2250LogicalChannelParameters & | param | ) | const [virtual] |
Fill out the OpenLogicalChannel PDU for the particular channel type.
param | Open 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.
param | Acknowledgement PDU |
Reimplemented from H323_RealTimeChannel.
virtual void H323_RTPChannel::OnSendRasInfo | ( | H225_RTPSession & | info | ) | [virtual] |
This is called when a gatekeeper wants to get status information from the endpoint.
The default behaviour calls the ancestor functon and then fills in the transport fields.
info | RTP session info PDU |
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 session could not be renumbered.
sessionID | New session ID |
Reimplemented from H323Channel.
