Method	Description
AudioChannel ( ) : System
AudioSampleReceived ( byte sample, int offset ) : void	Event handler for receiving an RTP packet containing and audio payload from the remote end of the VoIP call.
Close ( ) : void	Called when the audo channel is no longer required, such as when the VoIP call using it has terminated, and all resources can be shutdown and closed.
GetMediaAnnouncement ( ) : SDPMediaAnnouncement	Gets the media announcement to include in the SDP payload for a call.
GetSDP ( bool usePublicIP ) : SDP	Gets an SDP packet that can be used by VoIP clients to negotiate an audio connection. The SDP will only offer PCMU since that's all I've gotten around to handling.
SetRemoteRTPEndPoint ( IPEndPoint remoteEndPoint ) : void	Allows an arbitrary block of bytes to be sent on the RTP channel. This is mainly used for the Gingle client which needs to send a STUN binding request to the Google Voice gateway. Sets the remote end point for the RTP channel. This will be set from the SDP packet received from the remote end of the VoIP call.
StartRecording ( ) : void
