A、 Voice carrier stream utilizes Real-Time Transport Protocol (RTP) to carry the audio/media  portion of the VoIP communication.  

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

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

D、 Voice packets are encapsulated in TCP segments to allow for proper sequencing during  delivery. 

E、 Voice packets are very sensitive to delay and jitter.
