"3. EdgeWater brings us this one: actively manage TCP streams from Internet to CPE to provide better quality for Voice."
I think this refers to items this post lists: http://www.voip-info.org/wiki/view/VOIP+and+VPN There are some merits to this where congestion isn't the problem but instead more nefarious things like throttling by an ISP. When *heavy* congestion is the problem, TCP is the enemy of RTP. Specifically you *want* packets to drop when there is congestion and not get re-transmitted or hold up transmission of the rest of the payload. Dropping 1,2 or 5 packets per second isn't likely going to be much of an issue depending on how dense or sparse the drops are in a particular sequence. This little blurb has always been helpful in explaining the concept to people: http://www.voiptroubleshooter.com/problems/packetloss.html In my opinion however the future of net neutrality becomes more of a major discussion point for VoIP over the public internet and ITSPs who want to support customers who bring their own bandwidth.

A few techniques to make voice across the Internet better: 1. For packets from the ITSP to the customer: override the default BGP routing to choose an alternate route 2. Increase the ptime from 20 ms to 30-40 ms to reduce packet-drop exposure 3. EdgeWater brings us this one: actively manage TCP streams from Internet to CPE to provide better quality for Voice. So what OTHER techniques are there? Which techniques don't work? Yeah, it's the Internet. It's going to have failures. You're going to have bad days. But surely there are ways to improve the odds. >>> m...@ecg.co +1-229-316-0013 http://ecg.co/lindsey ________________________________ This e-mail and any attachments are confidential.
