To Reproduce
Steps to reproduce the behavior:

  1. Connect to JsSIP public server like below:
await _sipuaHelper.start(
      UaSettings()
        ..webSocketUrl = "wss://edge.sip.onsip.com"
        ..webSocketSettings.transport_scheme = "WSS"
        ..webSocketSettings.extraHeaders = <String, dynamic>{
          "Origin": " https://tryit.jssip.net",
        }
        ..displayName = dest
        ..password = dest
        ..authorizationUser = dest
        ..uri = "sip:[email protected]",
    );
  1. Make call a from one device to other
  2. Once call get connected, try call.refer()
  3. you will get the above error

Expected behavior
Once fun call.refer() is called, it should processes the request and notifies the involved parties, ultimately establishing a new call leg to the new destination.
