The main technical issues for BUNDLE at the moment are:

1)	How to demux RTP (and other media types, but RTP is the most critical). This is currently discussed within the "Plan A vs Plan B" context on the RTCWEB list.

2)	Where to send media until an O/A exchange with identical port number has taken place. This is currently discussed on the MMUSIC list ("Bundle offer with different ports - where to expect media?").

Since it seems that many of the key draft authors of the Plan A vs. Plan B discussion are unable to attend the virtual interim at the planned time, we have decided to focus at this interim on the open issues in the Bundle draft.

For details please read the current Bundle draft:

Also see the latest Bundle threads on the MMUSIC mailing list. Christer will provide a more detailed list of issues to discuss.
