在React Native中集成Voximplant实现语音通话：完整教程

// VoxEngine Scenario: handle_incoming_calls.jsVoxEngine.addEventListener(AppEvents.CallAlerting, (e) => {  // 当有呼叫提醒事件时触发  // e.call: 传入的呼叫对象  // e.destination: 呼叫的目标用户  // e.displayName, e.callerid, e.headers: 呼叫的附加信息  // 使用 callUserDirect 将传入的呼叫直接路由到目标用户  const newCall = VoxEngine.callUserDirect(    e.call,    e.destination,    {      displayName: e.displayName,      callerid: e.callerid,      headers: e.headers,    }  );  // 使用 easyProcess 简化呼叫处理流程，自动处理媒体流和连接  VoxEngine.easyProcess(e.call, newCall, ()=>{}, true);});
