Hi Kaiser,
First of all if it's about an existent call, the UA must send only BYE,
not CANCEL (at t1).
Anyhow if a re-INVITE is received after BYE was sent, it must be
rejected by the UA. Re-INVITEs are requests within dialog, and via BYE
the UA close the dialog, so the re-INVITE will not match any dialog.
So definitely it will not be a new call.
Best regards,
Marian

Hi,
I have a question that if a proxy send a re-invite to a UA, and almost
at that moment, UA hangup. If network is slow, the packet delay could
cause a funny situation. That UA ring after hangup...
For example
t0(0 sec):proxy send reinvite to UA to a existed call
t1(0.1 sec):UA send BYE or Cancel to proxy, because user hangup,
t2(0.2 sec):UA receive the reivite from proxy.
at this senario, UA receives an re-invite "INVITE" , would this
reinvite cause the IP-phone ring when "hangup"?
Of course, this is not always happen, but it could be happen, right? The
Cseq is different, UA would treat the re-invite as a new call. Is it right?
best regard
