I support Stephen's discusses.

REQ-012 refers to "the identities of parties involved". The term "identity" is
vague. I suggest changing "identities" to "identifiers" or, even better, "SIP
identifiers" or "SIP addresses".
In REQ-024, what is "wall clock time"?
Regarding terms such as "authentication", "confidentiality", "encryption", and
"integrity" in REQ-025 through REQ-032, an informational reference to RFC 4949
seems appropriate.
