Hey , Greetings of the day
having the delivery issue for some of the extensions .
Message Status is 'SendingFailed' for all the message .
Checked the Extension Info API Also .
 => stdClass Object ( [featureName] => SMS [enabled] => 1 )  => stdClass Object ( [featureName] => SMSReceiving [enabled] => 1 )
As you can see the SMS Feature is on
But still the SMS' are not being delivered .
We are facing the issue for two users and for rest users it is working fine .
