#12 Expires timer for invoming INVITE

[Pekka Pessi]

Mail by Roman Filonenko:

RFC3261, section 13.3.1 ("Processing of INVITE") has a following bullet:

If the request is an INVITE that contains an Expires header
field, the UAS core sets a timer for the number of seconds
indicated in the header field value. When the timer fires, the
invitation is considered to be expired. If the invitation
expires before the UAS has generated a final response, a 487
(Request Terminated) response SHOULD be generated.

I suppose that to implement the above, one needs to define a separate
dialog usage (like nua_session_usage). Is that correct?

Is the bullet planned for implementation?
