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

Ethereal Users:-  Is that correct statement

"Ethereal don't have jitter buffers when they strip out the voice so I
presume they are just taking the voice payloads and converting them to a
stream as they get them and further into the analog voice sample heard in
the audio. This is why I think we hear good voice from the stream and why it
could be garbled when processed by the system"
