Need help for solving webRTC issue in chrome version 63 .

Sasmita Panda
Hi All ,

     I am using opensips-2.2 with wss and rtpengine module . 1 end point is pjsip and other is webRTC and opensips is acting as a proxy in-between to handle media and acting as a gateway for webRTC and SIP .

      Everything working fine when I am using Chrome version 62 , but when I upgrade to 63 its giving some error like
  " OperationError: Failed to set local sdp: Session error code: ERROR_CONTENT. Session error description: Cryptos must be empty when DTLS is active. "

          Can anybody suggest me how to remove this crypto from INVITE message so that Chrome will accept it .  I think I need to change something in opensips side but not getting any appropriate method .
    
      Please help , I am blocked in production environment . 

      
  
Thanks & Regards

In WebRTC M63, Applying a session description with both “a=fingerprint” (for DTLS) and “a=crypto” (for SDES) will now fail; the offerer must decide on one or the other .

While updating SDP , opensips is sending both . I am using below option for updating SDP .

$var(rtpengine_flags) = "UDP/TLS/RTP/SAVPF rtcp-mux-offer ICE=force DTLS=passive";

What should I do so that either crypto or fingerprint will go in SDP .

Thanks & Regards
