Atif,
  Ethereal definitely doesnt have a jitter buffer. But I dont know how it
handles the out-of-order packets. Intuitively, I think, that it just stores
them as they arrive. It might as well reoerder them to bring them back in
the right sequence.

What might aid in achieving a good quality is that becuse it does not have a
jitter buffer and that u dont have to deal with the playout delay syndrome,
the the packets arriving too late are not discarded.

If ethereal reorders the packets, then u may find very good quality: The
only impairments would be due to packet loss occuring at intermediate nodes
due to congestion (given a particular codec).

I hope this helps a bit.

Regards,
Adil Raja
