Given a call flowlike the one shown, you could consider using redirects from the registrar
rather than passing traffic through the registrar. I agree that this does very much feel
like a place where a B2BUA is appropriate given what may be a very non-standard
implementation by another UA. With that said it's fairly cheap and easy to add more
kamailio to any environment - even use alternate ports as needed and run it in a
container.

So the call flow is:
Alice => Registrar => Core => Registrar => Bob
The same call passes the registrar twice. This, as I observe (it's
still possible I did something wrong), breaks topos and header get
replaced the wrong way!
As far as I know, this situation badly cries out for a lightweight B2BUA. It's no
accident that pretty much all SBCs are based on a B2BUA.
However, I could be mistaken...
