Description (last modified by bennylp) (diff)

Currently media transport attributes transmitted by refresher is not really generated by media transport, it is just resending current active local SDP. Currently, it works fine while depending on an assumption that the attributes do not change since from the initial offer/answer.

The problem is because transport's encode_sdp() callback is not called to "bless" the SDP. While the transport's media_start() will be called, some transports may get upset because of this.

With #1047/#1097, we will send UPDATE without SDP if remote supports UPDATE, hence making this issue less critical.

Moving this ticket to Known-Issues.
