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 |

|
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 |
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.

Fill out the OpenLogicalChannel PDU for the particular channel type.
param | Open PDU to send. |
Reimplemented from H323_RealTimeChannel.
|
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 |
Handle channel data reception.
This is called by the thread started by the Start() function and is typically a loop writing to the codec and reading from the transport (eg RTP_session).

Start the channel.
Reimplemented from H323UnidirectionalChannel.
|
virtual |
Handle channel data transmission.
This is called by the thread started by the Start() function and is typically a loop reading from the codec and writing to the transport (eg an RTP_session).
