The thing I keep asking is can we make a list of reason why SDP and headers get changes and in what scenarios they do this. I think it will be hard to sort how to fix this without being clear what needs to be fixed.

For example, one of the things we might want to say is something like: the Phone is behind a NAT and connects to it's proxy / registrar for its' domain. That proxy/b2bua whatever mucks with IP/ports in the SDP for NAT traversal. Then we could ask if 4474 is broken in this case or not and what might be a good way of solving the problem of having UAs behind NATs.
