Hi,

Just to be clear, with “WebRTC endpoint” I guess you do not include gateways?

Maybe we should talk about “JSEP endpoints”, or something..

Regards,

Christer

Yes. In the offers and answers that WebRTC endpoints create, a=ice-lite is prohibited, since WebRTC endpoints must support "Full" ICE.

The remote endpoint may of course support only ICE Lite, and WebRTC implementations must work properly with such endpoints.

This isn't normatively indicated anywhere that I could find, so I plan to add specifics on this to the next version of JSEP.

Without reading JSEP-04 I expect that it is not allowed for a web
browser to indicate "a=ice-lite", but a server can do that. Anyhow,
AFAIR the usage of ICE lite is fully transparent for the non ICE lite
endpoint.
