Voice users in a new VoIP network have been complaining about the poor quality of voice over the WAN. They claim that conversations seams to incur talker overlap in which talkers and listeners become unsynchronized and often find themselves speaking at the same time or both waiting for the other to speak. Which two actions could you take that would most likely resolve the problem? (Choose two)

A.
Increase the link speed.

B.
Enable fragmentation on the WAN link.

C.
Enable RTP header compression on the WAN link.

D.
Increase priority queue size.

E.
Increase de-jitter buffer size.

Explanation:
Voice packets may be getting stuck behind large data packets, fragmentation will reduce the overall size of data packets so voice packets don’t wait so long to be transmitted. RTP header compression will reduce the total bandwidth needed for each voice call
