AWS sms-voice documentation change
Summary
Clarified messaging routes and costs for India, specifying that international (ILDO) routes work from any AWS Region, while local routes with DLT-registered sender IDs are only supported from AP-SOUTH-1 and AP-SOUTH-2, and added a reference to the India sender ID registration guide.
Security assessment
The change adds documentation about a regulatory compliance feature (DLT registration for sender IDs in India) which is a security and anti-spam measure. It clarifies regional support for secure, registered local routes versus more expensive international routes. This is an update to operational and compliance guidance, not a fix for a disclosed security issue.
