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 kaiser ------------------------------------------------------------------------ _______________________________________________ Serusers mailing list serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers
