This document defines the requirements and a proposed solution for an SDP Offer/Answer exchange model for negotiating best-effort SRTP keys, i.e., in a backward-compatible manner with non-SRTP devices. The proposed solution is a trivial interpretation of the usage of the profile and the usage of SDP indication of [sdesc] and [kmgmt].
