Hi,



Do we really need to say more than the ICE RFC already says? I think it explains when ICE-lite is appropriate, and when it isn't.



Regards,



Christer

The spec should say that:
1. The prohibition on sending media prior to completing a STUN
connectivity test is a MUST
2. A full ICE implementation is a SHOULD

If I'm building a system with clients at one end and gateways with
public addresses at the other, a full ICE implementation isn't required
anywhere in order to make calls through those gateways. But keeping the
browser from being able to spew media at something that hasn't consented
*is* required.
