             Summary: Asterisk producing ICE candidates with same priority
                 Key: ASTERISK-30475
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-30475
             Project: Asterisk
          Issue Type: Information Request
      Security Level: None
          Components: Applications/app_ices, Channels/chan_pjsip
    Affects Versions: 18.16.0
         Environment: Ubuntu 18.04
            Reporter: Arun
            Severity: Critical

I am using kamailio and asterisk together where jssip client registers with kamailio. I have created a pjsip endpoint in asterisk with webrtc = yes. Kamailio and asterisk is in same network and call is dialed from webrtc client. Asterisk sending back callprogress. I don't have voice at all. I have checked the ice candidates and found that asterisk is sending its private and public candidates with same priority and because of that reason ICE is getting failed in kamailio side. I will attach the sdp logs on asterisk of both direction.
