Re: [reSIProcate-users] a question about dialog of dum
i don't really agree that "DialogSet's are keyed off of call id and from tag"
it think it should be "DialogSet's are keyed off of call id and local
tag" if the "DialogSetId::DialogSetId(const SipMessage& msg)" is
true.
yestoday,i test that sending a invite but not really,and then i use
setFromExternal() to it ,force it to
DialogUsageManager::processRequest ,then i got two dialogset.
so i get that a almost same invite request but one from out
(isExternal) and one from tu.the dialogsetid should be different,then
it will create two dialog.
the thing above is my question,now i get it and i have to say my
expression is so bad.
