Hi Bogdan,
Yes, that's correct.
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.
Let me know if I can provide any further information.
Many thanks,
Callum

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

Hi OpenSIPs Community,
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.
To help illustrate, here is an example control port sequence of a
properly engaged call:
65098_11 *UR*8.8.8.8c9,8,0,3,101,13 */the-call-id/*
192.168.153.223 10248 */from-tag/*;1
65118_19 *LR*8.8.8.8c8,101 */the-call-id/* 192.168.153.223 10248
*/from-tag/*;1 */to-tag/*;1
In my scenario the *UR* (create session) request was never
received. Without claiming any expertise on the rtpproxy protocol
this was clearly not correct and the *LC* (update session)
request could not locate a session to act on.
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.
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.
Thanks!
Callum
