Hi,

The new text says:

   “In certain scenarios when either no candidates were provided in the
   offer or all the provided candidates were discarded (say, due to
   unsupported address type or FQDN name resolution failure), the
   answerer MUST NOT consider this as immediate ICE processing failure
   but instead MUST wait for the peer reflexive candidates to arrive to
   carryout the connectivity checks or eventually time out on the
   connectivity checks (see [draft-holmberg-ice-pac]).”

I don’t think we shall have these MUST NOT and MUST.

As I have commented in the ICE WG, ICE PAC only gives guidance on how long to wait before declaring ICE failure, but an agent is still allowed to declare ICE failiure whenever it wants without being non-compliant with the spec.

Also, since ICE PAC is generic ICE, I don’t think ice-sip-sdp shall add any normative text in addition to what is already included in ICE PAC.

However, I do agree that referencing ICE PAC is a good idea, but perhaps it’s enough to say that ICE PAC gives guidance.

Regards,

Christer
