Acceptable jitter on the WAN

Hi there,

I am deploying IP telephony across a WAN and my WAN guys are asking what is the maximum jitter I will accept. I have read all the CCO documents I could find but no guidelines as to an acceptable jitter range for AVVID.

I am using 79xx phones and 12.2 IOS MGCP gateways with default playout.

I have the "150ms" figure for delay, but nothing for jitter.

Thanx,

Eric Morgan

Re: Acceptable jitter on the WAN

From Cisco Networkers 2002 in Orlando in the handout for the session entitled " Design Guidlines for Voice over IPSec VPN Deployments"

Packet Loss <=1%

Delay<=60ms One Way

Jitter<=20ms

Maybe not exactly what you needed but the quickest thing I could come up with. If I see anything else I will pass it on.

Hello Eric,

I found a Cisco pdf that states

loss<1%

delay 150-200ms

jitter 30ms
