At SIPNOC this week, we're having a "Birds of a Feather" session on delivering quality voice services across the public Internet.

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.
