That is crucial, undocumented (as far as I know) information. The external IP in my case is publicly visible.

Oh, excellent. That's the missing piece of the puzzle: an internal profile. I didn't realize that was necessary, since it _almost_ worked in a single profile that did both. Use of the single profile is no doubt why I needed ext-sip-ip defined to get this working even partially.

Now comes some testing and experimentation, to put it mildly.

Thank you very much!
