Lelio, I think you are looking for IP SLAs feature on IOS, its a particular feature set that can run tests for delay, packet loss, jitter, etc. I've never used it personally but I remember hearing about it a few times. If you use it let me know what you think :)

delay isn't over<br>> 150 ms or so, you should be fine. As I recall, the
maximum<br>> *round-trip* delay over a WAN for a subscriber is 40 ms, which
is<br>> pretty stringent.<br>><br>>
