Please don’t paste huge chunks of unformatted text in your posts, without a single explanation of the problem. I fixed the formatting for you, but please do better next time you ask a question.

That said, looking at the SDP it’s clear to me you’re using a modified version of Janus, and not a clean one. Please test an unmodified version of Janus and let us know if the problem presents there (which I don’t think it will).
