<tt>When OpenSIPS handles the SIP messages carrying SDP (typically
INVITE request and 200 OK reply), OpenSIPS will communicate with
rtpengine and update the SDP with the new IP and port. Never
tested, by AFAIK rtpengine may know to handle SRTP...not sure, you
may check with the project.<br>

<div>Ok. Incase if the media needs to go via rtpengine, then
how the signaling happens, and how the rtpengine is
forwarding the media to the other end?<br>
<br>
</div>
<div>In case of DTLS, only the DTLS handlshake needs to be
taken care by the RtpEngine, and the SRTP is handled by some
other media server, and only the DTLS-key needs to be send
to the media server. In that case, how can we fetch dtls-key
after the DTLS handshake?<br>

<br>
There are no SDP answers created by opensips - it simply
changes the received SDP offer and it forwards it to the
next destination - basically it is doing proxying
(performing some changes too) of the SDP offers between
the end points.<br>
<br>
Best regards,<br>

<div>Hi all,<br>
<br>
</div>
<div>How is the communication flow happens
between opensips and rtpengine incase of a
call through SIP over websocket?<br>
</div>
<div>When opensips receives a sdp offer from a
web-based sip client, opensips is creating sdp
answer or rtpengine is creating sdp anwer or
rtpengine just updating ice information only
in sdp and other than that, media related info
is created by opensips?<br>
</div>
<div><br>
</div>
Thanks.<br>
