SimpleUser Media Do Not Request or Use Local Audio Source

[David Plappert]

I am trying to only listen to a remote call. I do not want the local user's microphone or webcam to be used or requested. This is my code so far, but it does not function as I intend. I can remove the line "exact:null" and my code works for calling, but it still asks permission for my mic.

const options = {

  media: {

    remote: {

      audio: this.$refs.remoteAudio,

    },

    constraints:{

      audio:{

        deviceId: {

          exact: null,

        }

      },

      video:false

    }

  },

  userAgentOptions: {

    authorizationPassword: pass,

    authorizationUsername: user,

  }

};

const server = "wss://" + domain;

// this sets up the main object

this.sip_SimpleUser = new this.$Sip.SimpleUser(server, options);
