Re: [webrtc-pc] Missing CNAME in RID based simulcast offer (#2114)

"While support for signalled SSRC identifiers is mandated, their use
   in an RTP session is OPTIONAL.  Implementations MUST be prepared to
   accept RTP and RTCP packets using SSRCs that have not been explicitly
   signalled ahead of time."

I read that as "you need to be able to receive SDP with SSRC in it", but every implementation also needs to be prepared to receive SDP without SSRC.
