Flowroute: DIDs -> select number -> Choose a DID Action -> Set callback URL -> Apply action -> check SMS Callback, SMS DLR callback (?) -> enter URL complying with https://developer.flowroute.com/api/numbers/v2.0/set-a-messaging-callback-url-for-phone-number/ https://developer.flowroute.com/api/numbers/v2.0/set-a-messa...
