Hi,

An intermediary doesn't have to do BUNDLE, and the intremediary can act as ICE lite, and things will still work fine with the rtcweb client.

Regards,

Christer

Hi,

As I've mentioned before, we should really try to avoid solutions that require intermediaries to send reINVITEs - or, more general, send SDP offers.

Regards,

Christer

If you stick to that rule, you'd want rid of ICE, SRTP, BUNDLE and all the other things an intermediary may have to add
to a plain legacy device's offer in order for it to be acceptable to a browser.

Or in other words: Why is the DTLS re-write especially irksome . ?
