<div dir="ltr">Hi David, <div><br></div><div>Thanks for the response, the problem is i'm running pcscf within a pod and reboot will not help in my case. But the issue is resolved when i reinstalled linux-headers. Now it starts without any errors. I got the following logs while starting pcscf.</div><div><b>1(5087) INFO: rtpengine [rtpengine.c:2750]: rtpp_test(): rtpengine instance <udp:localhost:2223> found, support for it enabled</b></div><div>But when i made sip call, packet capture shows rtp flow between two sip client address. It means the packets are not flowing through proxy right?(If not please suggest me how to verify it) Does this log guarantees that proxy is setup or anything else to be done.<br><br></div><div>Kindly help me with this issue.</div><div><br></div><div>Regards,</div><div>Pavithra </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Oct 14, 2020 at 9:54 PM David Villasmil <<a href="mailto:david.villasmil.work@gmail.com" target="_blank">david.villasmil.work@gmail.com</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="ltr">I believe you need to add the table yourself like:<div><br></div><div><a href="https://github.com/sipwise/rtpengine" target="_blank">https://github.com/sipwise/rtpengine</a></div><div><br><div><br></div><div><pre style="box-sizing:border-box;font-family:SFMono-Regular,Consolas,"Liberation Mono",Menlo,monospace;font-size:13.6px;margin-top:0px;margin-bottom:16px;padding:16px;overflow:auto;line-height:1.45;background-color:rgb(246,248,250);border-radius:6px;color:rgb(36,41,46)"><code style="box-sizing:border-box;font-family:SFMono-Regular,Consolas,"Liberation Mono",Menlo,monospace;padding:0px;margin:0px;background:initial;border-radius:6px;word-break:normal;border:0px;display:inline;overflow:visible;line-height:inherit"># this only needs to be one once after system (re-) boot
