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

B、 Because a packet loss involves a small amount of data， voice traffic is less affected by packet losses than traditional data traffic is.

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.
