Re: [Sip] Draft submission: draft-ietf-sip-199-00

Christer,
Should the 199 response contain a Contact header? And if yes, in case a proxy sends it, should it contain the address of that proxy (since the UAS already sent a final response)?
Should we say that a proxy may only generate and send a 199 when it receives a final error response on an INVITE client Transaction which was in the PROCEEDING state? (i.e. 1xx response was received before, so conceptually sending the 199 response is an action associated with the transition from PROCEEDING to COMPLETED) 

Regards,
Jeroen

Hi,

I agree it may be a good idea to not forbid sending it reliably.

I do think it would be good to have text, saying that it can be sent unreliable even if reliable responses are required, though, so that proxies aren't forced to terminate PRACKs etc.

Regards,

Christer

   [CHH] Whether the text should be in the document at all depends on if we
   allow 199 to be sent reliably in the first place. Based on the comments
   received so far we should not mandate 199 to be sent reliably, even if
   100rel is required by the UAC. But, the question if whether we want to
   FORBID sending it reliably.

If we ever might allow 199 to be used for HERFP, we should admit the possibility of sending it reliably in the first draft.  Otherwise, we'll be locked out of sending it reliably in the future.

Dale
