You MUST sign in order to be able to use DTLS-SRTP effectively. This
means that even PSTN-grade identities have to be signed. So we we either
have to change DTLS-SRTP to not have this dependency, or we have to find
a way to mark the PSTN-grade ones appropriately so that they are not
taken seriously as a strong identity.

Adam's approach solves this better than us1ing PAID, as 1) we could NOT
have DTLS-SRTP (a standareds-track doc) with a normative reference to
RFC 3325 (an informational track doc). Further, the same problem applies
-- even with RFC 3325, it would be good to differentiate strong
identities from PSTN-grade identities.
