</div>
<div>Yes, that's correct. </div>
<div><br>
</div>
<div>In my scenario I created the dialog, engaged rtpproxy and
then performed an async rest_post. The result was that the
session creation was not triggered on the remote rtpproxy.</div>

<div>Let me know if I can provide any further information.</div>

Shortly said, if you do rtpproxy_engage() *before* an
async call, the create session is not triggered ?<br>

<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>
