You can intruduce a predefined amount of "distortion" on your ip-connection
(packet loss, fluctuating delay, out of secuence reception of packets,
limited bandwith)

All of these will have a serious impact on your VOIP-connection.

See "lartc" about it.
Good thing about it, is that you pre-define how bad a line is, and it
produces re-producable results
