                    <div dir="ltr">Hi OpenSIPs Community,
                      <div><br>
                      </div>
                      <div>I wanted to report an issue I discovered when
                        attempting to use the rtpproxy module, using the
                        dialog backed rtpproxy_engage() function.
                        Finding that it was not engaging in certain
                        scenarios I took a closer look at the activity
                        on the control port and discovered that OpenSIPS
                        never sent a request to open the session in this
                        scenario.</div>
                      <div><br>
                      </div>
                      <div>To help illustrate, here is an example
                        control port sequence of a properly engaged
                        call:</div>
                      <div><br>
                      </div>
                      <div>65098_11 <b>UR</b>8.8.8.8c9,8,0,3,101,13 <b><i>the-call-id</i></b>
                        192.168.153.223 10248 <b><i>from-tag</i></b>;1<br>
                      </div>
                      <div>65118_19 <b>LR</b>8.8.8.8c8,101 <b><i>the-call-id</i></b> 192.168.153.223 10248 <b><i>from-tag</i></b>;1 <b><i>to-tag</i></b>;1<br>
                      </div>
                      <div><br>
                      </div>
                      <div>In my scenario the <b>UR</b> (create
                        session) request was never received. Without
                        claiming any expertise on the rtpproxy protocol
                        this was clearly not correct and the <b>LC</b> (update
                        session) request could not locate a session to
                        act on.</div>
                      <div><br>
                      </div>
                      <div>Following a fairly lengthy investigation I
                        traced the issue back to my usage of the async()
                        function where i was issuing the
                        rtpproxy_engage() request before calling async
                        for another purpose. The solution was simply to
                        move the rtpproxy_engage() call to after the
                        async method.</div>
                      <div><br>
                      </div>
                      <div>I'm happy that the issue is resolved for my
                        requirements however I thought I would share the
                        experience to the list in case others found
                        themselves having a similar issue.</div>
                      <div><br>
                      </div>
                      <div>Thanks!</div>
