I am getting the following error when trying to send an SMS from a phone number assigned to a different user in my account. The error message makes mention of the "OutboundSMS" permission, but I do not see that permission in my account. Here is the error I am getting from the API:
{
"errorCode": "FeatureNotAvailable",
"message": "In order to call this API endpoint for another extension, one
of the following permissions [OutboundSMS] have to be granted
extended scope to the authorised user.",
"errors": [
{
"errorCode": "CMN-419",
"message": "In order to call this API endpoint for another extension,
one of the following permissions [OutboundSMS] have
to be granted extended scope to the authorised user.",
"permissionsName": "OutboundSMS"
}
],
"permissionsName": "OutboundSMS"
}
