The debug log should tell you what is going on then with the handling of
the streams. It's spread across res_pjsip_sdp_rtp, res_pjsip_session, and
then the bridge modules. I don't have specific line numbers because there's
lots and lots involved. The "core show channel" CLI command can also
provide insight.
