Hi all, While doing some reading today I got a bit confused about how to express optional SRTP on an SDP. The right way seems to be to add 2 audio streams, one with SRTP and another one without:
- Stream without SRTP: RTP/AVP transport. - Stream with SRTP: RTP/SAVP transport and a=cryplo lines. Am I right here? I've seen another way of doing this which looks 'not standard': use RTP/AVP and a=crypto lines when SRTP is optional. Sofia SIP stack generates a warning in this case (according to a FreeSWITCH users list thread) but PJSIP allows this to happen silently for example. I've also seen this in different clients out there, so, what is the right way of specifying that *optional* SRTP support is required? Thanks in advance for any hint.
