i don't get that impression:

     * For a SIP Reply it returns true if the reply belongs to an existing
       transaction and false otherwise.

if i get two 200 oks to the same invite, both of them belong to an
existing transaction.  the thing i want to know is if reply is the first
reply or a retransmission of the reply.
