Hello, trying to think a bit more about it, I guess that what happens there is the following:
- re-invite comes it - loose_route() is executed and by that uac module has the callback for updating To/From executed - you update the sdp and then call apply changes, which updates also the headers - transaction is created with the new values for From/To headers If my assumption is right, then the solution would be to do the updates and apply changes before calling loose_route().
