Engineering safeguards
Trust the boundary. Verify the result.
Technical credibility comes from specific checks and honest limits. These are the safeguards present in the source, and the responsibilities they do not replace.
Authorised activation
Signed claims over HTTPS, validated service identity and bounded entitlements.
Protected configuration
Verified ownership, native object identities and fingerprint checks before change.
Isolated resources
Customer, product and item scope, immutable receipt origins and current per-number authority.
Controlled effects
Replay protection, bounded requests, audit records and explicit handling of uncertain outcomes.
The PBX is not your entitlement authority.
Root access controls the local machine. Commercial limits and upstream authorisation must remain enforced by the operator. The module is not an anti-tamper mechanism against the PBX owner.
Authorisation modelProduction adapters must enforce the contract.
Real authentication, CSRF, carrier scope, assignment locks, durable idempotency and shared limiting cannot be inferred from interface names. Prove those guarantees in the deployed operator environment.
Security and operations guideHandle sensitive information deliberately.
Do not post credentials, keys, emergency addresses or customer records in public repository issues. This site makes no claim of a dedicated private disclosure channel or response commitment. Use an established private relationship with the responsible operator for service-specific incidents.
