Case Files Professional 3.4.0 - SMS Connection Test

Agency Setup > Notifications includes a test recipient field and Send SMS Test.
Only administrators can send tests. Save the Twilio Account SID and Auth Token
under API Credentials, then save the SMS sender under Notifications.
Enter a recipient in international format, such as +17185551234.
The test submits one fixed message immediately, without waiting for CRON.
It contains no case details. Normal Twilio messaging charges apply.

A successful submission reports Twilio acceptance and the message SID.
Acceptance is not confirmed handset delivery: check the recipient phone and
Twilio messaging logs. Trial accounts require a verified recipient number.
The page reports common Twilio error codes without exposing credentials.

CSRF protection, a one-use test token and five attempts per administrator
per ten minutes prevent repeated sends. A page refresh does not resend.
Uncertain network responses are not automatically retried; check provider logs
before intentionally starting another test. Test attempts are audited with
only the recipient's last four digits and the provider reference where known.
