• A、 Voice traffic data flow involves large volumes of large packets.

• C、 Voice carrier stream utilizes Real-Time Transport Protocol （RTP） to carry the audio/media portion of VoIP communication.
• D、 Voice packets are very sensitive to delay and jitter.
• E、 Voice packets are encapsulated in TCP segments to allow for proper sequencing during delivery.
