                          <div>Hi,<br>
                            <br>
                          </div>
                          I'm trying out the b2b module on opensips and
                          have encountered an issue regarding PRACK.<br>
                          <br>
                        </div>
                        <div>In particular I have a scenario where the
                          called number replies with a 183 session
                          progress (Require: 100rel and RSeq: 1) and
                          then a few seconds later with a 180 Ringing
                          (Require: 100rel and RSeq: 2).<br>
                          <br>
                        </div>
                        <div>What happens is that opensips correctly
                          replies with a PRACK to the 183 response but
                          then doesn't do the same when it receives the
                          180 provisional response.<br>
                          <br>
                        </div>
                        <div>Excerpts from the logs show this happening
                          when the 183 message is received:<br>
                          <br>
                          Aug  9 17:31:14 [2528]
                          DBG:b2b_entities:b2b_tm_cback: Found require
                          hdr<br>
                          Aug  9 17:31:14 [2528]
                          DBG:b2b_entities:b2b_tm_cback: Found 100rel
                          header<br>
                          Aug  9 17:31:14 [2528]
                          DBG:b2b_entities:b2b_send_req: start type=1<br>
                          <br>
                        </div>
                        <div>but when the 180 response arrives, there
                          are no similar entries.<br>
                          <br>
                          It is my understanding that from a SIP
                          signalling point of view the b2b module should
                          reply with a PRACK to the 180 response too or
                          am I missing something ?<br>
                          <br>
                        </div>
                        <div>Any ideas as to why this may be happening
                          or could it be a bug ?<br>
                          <br>
                        </div>
                        <div>Many thanks,<br>
                        </div>
