<div dir="ltr">Collins,<div><br></div><div>This documentation is a bit dated but it explains the core concepts of using opensips with a webrtc client and a standard sip peer such as your CUCM. Not sure if you require a registrar so anything dealing with those methods can be removed. You should look into using wss in opensips and understand how rtpengine can facilitate the translation between A webrtc SDP which includes ICE peers with
<span style="color:rgba(0,0,0,0.87);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:14px">RTP/SAVPF</span> to standard SDP with RTP/AVP which is most likely what your CUCM requires. Consider that your CUCM might not support ICE so you may need to use the methods explained the article to remove those. Good luck</div><div><br></div><div>Thanks,</div><div>Tito</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Thu, Jan 23, 2025 at 7:17 AM Collins ONYEGBADO <<a href="mailto:onyegbadocu@fuotuoke.edu.ng">onyegbadocu@fuotuoke.edu.ng</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Dear support,<div dir="auto">I am a newbie in opensips.
