Hi, John, I like the idea, and your draft is more than a skeleton plus examples. There are a couple of concepts that could be added if you could come up with non-perjorative names... - "Filtered" actually splits into a few possibilities - the service provider may actually be "filtering" known services, or may be using NAT+ALG so that "unknown" services aren't available - not because the service provider said "no", but because the service provider has to actually do something to accommodate a new service. - The client/server orientation doesn't explicitly handle peer-to-peer connectivity (unless all the SIP clients have to be servers so they can receive incoming phone calls). Saying "I want incoming phone calls" is different from saying "I'm running my own mail server".
