Hi Roman,

 

Where does the spec say that you are only allowed to include currently negotiated extensions?

 

Regards,

 

Christer

Hi Roman,

 

I don't have any technical issues with only offering what is "enabled".

 

 

I think the issue I have with the existing version of JSEP,  which is fixed in the new document, is that when an offer is generated, it does not include all "enabled" or "supported" extensions. The existing version of JSEP says only to include currently negotiated extensions, which seems like a mistake.
