Jitter WAN

What is an acceptable Jitter Rate for an SLA with a service provider?

MY provider is saying that they will guarantee that jitter will not go

above 10 milliseconds and it will be measured in 5 minute intervals.

This is an MPLS network and we will run IP voice over this network.

What amount of Jitter can cause voice communication problems? Is it 8

milliseconds?

Thank You for any responses, all responses are greatly appreciated.

Have a wonderful day.

Re: Jitter WAN

Yes, anything more than 8 milliseconds can affect voice communications.

To be honest, this is what the books may say.

In reality it depends on how well the adaptive jutter buffer works. And the cisco phones and routers are excellent in that.

For example I have satellite circuits with 350 ms delay (best case) with high jitter (200 ms is common), and the quality is surprisingly good!
