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
