TCP or UDP for VoIP

smohr

So in studying for the CCNA I first read Odom's book, which was ok, but I wanted a different approach so I'm now using Lammle's book. So here's my question:

In Odom's book it states that it is better to use UDP as error recovery doesn't make any sense for VoIP. However, in Lammle's book it states to use TCP so the segments can be sequenced in order to put them back together in the correct order.

Which one is it?

if a voice packet or series of voice packets are retransmitted late or retransmitted, what will be the result?
That will give you the answer?
