Hello,
I have set up a Voice/UDP jitter IPSLA between a local router and a remote site on my network. The latency to the site is 250ms. All looks ok except that I get some starange results for Packet Loss of 80%. I know this isn't really the case else I would have users screaming. A staight ICMP IPSLA looks ok. I'm wondering what exactly the IPSLA is measuing to get this results and why there is a loss source to destination, I can ping source to destination using extended ping without issue. . Can anyone help.
Here is a section of the output
