Hello,
I have some comments related to the patches, as I couldn't dig much into

This above is to catch PRACK, right? UPDATE should be sent after 200ok,
or is allowed also for early dialogs?
Just answering from a protocol point of view, without code review:
The main purpose of UPDATE is to update the sessions although there is a
pending INVITE transaction. Thus, yes, UPDATE can be sent although there
was no 200 OK to the INVITE yet.
