[OpenSIPS-Users] How to change media protocol?

[Dragomir Haralambiev]

Hi,

I do this but Opensips +rtpengine not converting encrypted media to normal.

 if (isflagset(SRC_WS) && isbflagset(DST_WS)) {
         $var(rtpengine_flags) = "ICE=force-relay DTLS=passive";
} else if (isflagset(SRC_WS) && !isbflagset(DST_WS)) {
         $var(rtpengine_flags) = "RTP/AVP replace-session-connection
replace-origin ICE=remove";
} else if (!isflagset(SRC_WS) && isbflagset(DST_WS)) {
         $var(rtpengine_flags) = "UDP/TLS/RTP/SAVPF ICE=force";
} else if (!isflagset(SRC_WS) && !isbflagset(DST_WS)) {
         $var(rtpengine_flags) = "RTP/AVP/SAVP replace-session-connection
replace-origin ICE=remove";
  }

rtpengine_offer("$var(rtpengine_flags)");
