I followed the instructions for the Quick Start App to send SMS in Python. Using the Sandbox credentials, the sms queues, but isn't delivered. I have confirmed that number has the 'SmsSender' feature. I have tried sending an sms to two personal mobile numbers as well as another RingCentral number that I know is able to send/receive sms. The status printed back is 'Queued'; when I check the messageStatus, they all show 'SendingFailed.' I'm not sure what I'm missing! Any help would be appreciated.
After the phone number info, the typical message info is as below:
{ "type":"SMS", "creationTime":"2021-07-01T17:38:30.000Z", "readStatus":"Read", "priority":"Normal", "attachments":[ { "id":9819398004, "uri":"https://platform.devtest.ringcentral.com/restapi/v1.0/account/299110004/extension/299110004/message-store/9819398004/content/9819398004", "type":"Text", "contentType":"text/plain" } ], "direction":"Outbound", "availability":"Alive", "subject":"Test SMS using a RingCentral Developer account - Hallo World.", "messageStatus":"SendingFailed", "smsSendingAttemptsCount":1, "conversationId":3060223407456103798, "conversation":{ "id":"3060223407456103798", "uri":"https://platform.devtest.ringcentral.com/restapi/v1.0/conversation/3060223407456103798" } }
