Hi everybody.
quick question for you guys.
How much max jitter can we have before our voice call start degrading severly ?
Is jitter of 1 msec too much to maintain good quality call ?
thanks

Hi
1 msec is absolutely nothing to worry about.
See : http://www.ciscopress.com/articles/article.asp?p=357102 which suggests 30 msec, but these things aren't hard and fast. Different devices have differnet jitter buffers, different codecs, etc etc.
I presume you are having voice issues? Any packet loss on the rx side?

Thanks Aaron.
I work for a tier 1 ISP, one of our customer has mpls vpn with us,our customer raised a issue about jitter, after we perform some packet capture we see jitter of 1 msec average which in my view is very negligible considering SLA of 3 msec but one of our senior engineer ( I am being a newbie and this being my first job) says 1 msec is alot which i did not believe but i did not want to argue :)
Anyway i appreciate your help.
