AWS sms-voice documentation change
Summary
Added section clarifying registration status requirements and sending behavior implications for unapproved sender IDs.
Security assessment
The change documents security-related behavior by emphasizing that only 'Complete' registrations are valid, preventing misuse of unverified sender identities. However, there's no evidence of addressing a specific vulnerability.
