Hi Magnus, what do you exacly mean with "legacy interoperability"?

If you mean interoperability with SIP or XMPP I don't think that is
"legacy" as both protocols define extended features for the media
plane (including security concerns). It's true that some very-basic
SIP deployments and devices just use RTP without ICE, media security
and so, but that's not a written rule.

Regards.
