Are you sure? IIRC the contact may change (the Route

They call them target-refreshing requests:
12.2: ...
Requests within a dialog MAY contain Record-Route and Contact header
fields. However, these requests do not cause the dialog's route set
to be modified, although they may modify the remote target URI.
Specifically, requests that are not target refresh requests do not
modify the dialog's remote target URI, and requests that are target
refresh requests do.
Oh my god! you are right... and I remember having a discussion about it some
months/years ago in sip-implementors. True true. The question is: what is a
"target refresh request"??
