I have not tested jitter, but I will now. 

I had some dropouts when one of my machines was "being bad", 
and while it didn't usually disco, it did drop call content. I was 
surprised it hung on to the call for as long as it did.
Longest I can attest to is about 25 seconds. I haven't gotten 
around to figuring out why it held the session at all.

Have you experienced any blocking on Vonage?
