AWS SNS:SMS开始失败，并显示“尝试连接电话的未知错误". [英] AWS SNS: SMS started to fail with "Unknown error attempting to reach phone"

问题描述

通常，我们的应用程序通过us-west-2和us-east-1发送交易SMS.不超过发送限制.几天前，发送事务性SMS停止工作.大约12小时后，AWS CloudWatch日志显示错误:"尝试接通电话的未知错误".过去，该电话号码已成功接收SMS.接收器位于德国.不幸的是，即使SMS发送失败​​，该API的响应代码仍为200(成功).

Normally our application is sending transactional SMS via us-west-2 and us-east-1. Sending limits are not exceeded. Some days ago sending transactional SMS stopped working. About 12 hours later the AWS CloudWatch logs show the error: "Unknown error attempting to reach phone". The phone numbers received SMS successfully in the past. The receivers are located in Germany. Unfortunately, the API's response code is 200 (success), even though the SMS is not sent successfully.

非常令人惊讶的是，成功发送了一些SMS.但是大多数SMS都会导致上述错误.即使通过AWS SNS控制台发送事务性SMS也无法正常工作.绿色的Flash-Message表示成功，但是没有发送SMS.

Very surprisingly, some SMS is sent successfully. But most SMS are resulting in the before mentioned error. Even sending transactional SMS via AWS SNS Console are not working. The green Flash-Message is indicating a success, however, no SMS is sent.

是什么导致此错误?是否有可能在我们的应用程序中检测失败的SMS?

What is causing this error? Are there possibilities to detect failed SMS in our application?

推荐答案

由于成功发送了一些SMS，但是大多数SMS却产生了以下错误:

Since some SMS are sent successfully but most of the SMS are resulting with the error:

Unknown error attempting to reach phone
