Hi Roman,

What about:

“…media packets in the any previously established DTLS association and…”

That covers both the currently established and already closed associations.

Regards,

Christer

I could do that. Or, I could use say "make sure that media packets in *any* existing DTLS association"

If we are nitpicking we need to define what "existing" DTLS association means here. In this particular case this means any DTLS association for which it still possible to receive packets. This includes currently established DTLS associations as well as any DTLS association which were closed but can still receive packets due to network transmission delays.
