I'm missing something here, what updates the dialog structure with the To tag once its been set?

[ovv]

Basically in the receive_message / receive_response of the dialogs

[ovv]

Do not merge yet. I'd like to do some more test after the rebase

[ovv]

So the tag gets added as part of the inbound processing? Okay, I think that might should be okay. Might be a little surprising if you dump the message as you don't see the original message anymore, but should be okay.

Yeah I thought about that. In the future the original message To and From should be a snapshot of the dialog To / From. That way we can update the details without changing the original message.

[vodik]

I think it might make sense to hide the original message and pull useful information out of the Request object - at least, that was my plan. I'm only half way there, which is why I left that class embedded right inside the dialog logic.

And in that case, it might make it easier to refactor if its turns out we can't put the tag on the message immediately - have it in the Request object instead.

I mean, in theory, we can do SIP forking (see #100) inside a single endpoint - an INVITE comes in and we send two distinct responses each with a different tag. Maybe the best API for this is to be able to fork the request object....

@moises-silva ^ ping if you don't mind.

[ovv]

Removed some more proxy stuff since it's not working.
I'll look into it in a future PR
