Hi,

>draft-ietf-mmusic-dtls-sdp-32 seems ambiguous on this point. The “Generating initial SDP offer” section is written from the assumption 
>the initial offer includes DTLS-SRTP. But the “modifying a session” section talks about putting a new offer for DTLS-SRTP in a subsequent SDP offer. 
>Taken as a whole, this seems more in the vein of “initial SDP offer” is really the initial SDP offer, and it just (reasonably) neglected to describe the 
>case where the initial offer does not include DTLS-SRTP.

The "initial offer" applies when a DTLS association is to be established.

"Modifying the Session" applies when a DTLS association has previously been established.

Regards,

Christer
