[cisco-voip] requirements for WAN link with centralized deployment

[Ed Leatherman]

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 :)

see if this helps: http://www.cisco.com/go/ipsla
