Re: [reSIProcate-users] a question about dialog of dum
the transactionid which has been said is in order to say that the
invite can be transmited to the dum beacause the invite we sent and
the invite we received are not in a transaction.
"A dialog is identified by a call identifier, local tag, and a remote
tag. "from rfc3261
the dialogsetid of the invite we sent is combination of call-id and
from tag(local tag)
the dialogsetid of the invite we recieved is combination of call-id
and to tag which we will create one(remote tag).then the dialogsetids
are different or not?and dialogsets aredifferent or not?and dialogs
are different or not?
ps:in processRequest of dialoguagemanager there is
findDialogSet(DialogSetId(request))
