Many boxes are able to reorder packets. If packets arrive too late to be inserted into the conversion stream, they are dropped. One dropped packet in a sequence can usually be 'hidden' or 'faked' by the codec. When more than one packet is missed in sequence, it becomes noticeable to the listener. Ray Burkholder

There is no reason to implement QOS on the Core.Having saidthat, there still seems to be too many issues on the tier 1 networks with pacekt reordering as they affect h.261/h.263 traffic.So what's the real problem here? Are the VOIP boxes unable to handle out of order packets? Do the out of order packets simply arrive far enough delayed to blow the delay budget? What percentage of reordered packets starts to cause issues? -- Leo Bicknell - bicknell () ufp org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request () tmbg org, www.tmbg.org
