Cannot create webrtc call using sip.js












0















I am not able to create a Webrtc call using sip.js on FreeSWITCH. I believe there are some issues with Freeswitch configuration, but I'm not able to figure out where the issue is and how to figure it out.

Any help would be highly appreciated. I've attached my console log:

    I am not able to create a Webrtc call using sip.js on FreeSWITCH. I believe there are some issues with Freeswitch configuration, but I'm not able to figure out where the issue is and how to figure it out.

    Any help would be highly appreciated. I've attached my console log:

      I am not able to create a Webrtc call using sip.js on FreeSWITCH. I believe there are some issues with Freeswitch configuration, but I'm not able to figure out where the issue is and how to figure it out.

      Any help would be highly appreciated. I've attached my console log:

      I am not able to create a Webrtc call using sip.js on FreeSWITCH. I believe there are some issues with Freeswitch configuration, but I'm not able to figure out where the issue is and how to figure it out.

      Any help would be highly appreciated. I've attached my console log:
