1.3.2 Data Transfer Sequence
The data transfer sequence simply transfers audio data from the client to the server. The client will encode captured audio data using the current audio format agreed on during either the initialization sequence or the format change sequence and send it to the server. The client first sends an Incoming Data PDU, which informs the server that the next packet will contain audio data. The client will then send the audio data in a Data PDU.
