          phoneNumber: customerPhone.toString(),
          success: (res) => {
            if (res.errMsg) {
              this.queryCallStatus(customerWid);
            }
          },
          fail: (err) => {
            const { errMsg } = err;
            if (errMsg != 'makePhoneCall:fail cancel') {
              wx.showToast({
                title: '打开会话失败',
                icon: 'none',
                duration: 2000,
              });
            }
          },
          complete: () => { },
