[asterisk-dev] Broken SIP dialog if INFO messagesreceivedbeforefinal OK

[Nick Lewis]

It is not clear to me that RFC2976 permits INFO during early media

   "It is necessary that the mid-session signaling information traverse
   the post session setup SIP signaling path."

"post session setup" implies to me that it is permitted only after the
INVITE transaction has completed (i.e. after OK/ACK). OEJ may know
better. Even if nesting of invite, reinvite and info transactions is not
explicitly prohibited by the RFCs it opens a can of worms from both
protocol and implementation perspectives and is unlikely to be worth all
the effort needed to support it.
