I don't think that including tags is a dirty trick. Dialogs are idenfitied by
triple callid-fromtag-totag, an INVITE may initiate multiple dialogs, and keeping
the information complete is clean. This information should be relatively unique
even if UAC fails to generate random values -- callee's From tag will be good then.

I'm not sure.
