Re: [reSIProcate] DialogSetID is not same between onNewSession and onRefer

[Karlsson <boost.regex@xxxxxxxxx>]

I have added a new method to DialogSetId for

size_t DialogSetId::hash2() const
{
    return mCallId.hash();
}

2007/12/20, Byron Campen < bcampen@xxxxxxxxxxxx>:

        The INVITE that you get will not have a local-tag (ie; a To-tag) in
it. This is part of the keying info in the DialogSetId. When you
respond to the INVITE, DUM will randomly choose a local-tag (the
remote end needs to choose part of the keying info because of
forking), and this local-tag will come back in the REFER, making the
DialogSetId different. Your best bet is to just use CallId + remote-
tag in this case (hash each, and xor the hashes, since that's what
DialogSetId does anyway).

Best regards,
Byron Campen
