我试过用Twilio传递信息
但我得到了认证错误：

{"code":20003,"message":"Authentication Error - No credentials provided","more_info":"https:\/\/www.twilio.com\/docs\/errors\/20003","status":401}

Account SID和Auth Token根据需要更改代码：

// Create environment variables (named below) with your Twilio credentials
client := TTwilioClient.Create(
  GetEnvironmentVariable('*************************a271d22b1'),
  GetEnvironmentVariable('*************************3647817'));
// Your Twilio phone number
fromPhoneNumber := '+12*******40';
// Your destination number (for trials, this needs to be your mobile #)
toPhoneNumber := '+**********20';
// Make a phone call
Writeln('----- Phone Call -----');

allParams := TStringList.Create;
allParams.Add('From=' + fromPhoneNumber);
allParams.Add('To=' + toPhoneNumber);
allParams.Add('Url=http://demo.twilio.com/docs/voice.xml');
// POST to the Calls resource
response := client.Post('Calls', allParams);
if response.Success then
  Writeln('Call SID: ' + response.ResponseData.GetValue<string>('sid'))
else if response.ResponseData <> nil then
  Writeln(response.ResponseData.ToString)
else
  Writeln('HTTP status: ' + response.HTTPResponse.StatusCode.ToString);
