Callback
The practice of ending an unexpected or suspicious call and independently dialing a phone number obtained from your own prior records, never from the caller or from anything the caller provided, to verify a claimed identity through a channel the caller cannot control. (see Topic 1.3)
Defined in 2 GAGE programs, which carry 12 distinct definitions of it. The wording above is taught in Senior AI Scam Defense.
How each discipline defines it
The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.
The four-step verification behavior taught in this topic: end the current call completely, find a phone number from a source the caller never touched, dial that number, and ask directly whether the situation described in the original call is real. The core defense against voice-based impersonation of any kind.
A function registered with a subscriber (or timer) that the ROS 2 executor calls when a message arrives. Callbacks should be fast and non-blocking to avoid starving the executor and causing missed messages.
The practice of ending a suspicious contact and independently calling a phone number you already had, printed on your own card or statement, rather than any number provided during the suspicious contact itself. (see Topic 1.3)
The verification step taught in Topic 1.3, performed after the active pause ends a contact: calling back a person or institution using a phone number the learner finds independently, never a number supplied by the original caller. (see Topic 1.3)
The verification habit taught in Topic 1.3: hanging up on an incoming call, finding a phone number independently (never from the caller), calling that number, and asking whether the situation described is real. (see Topic 1.3)

Where it shows up at work
A definition is where Callback starts. The lessons above teach it inside the competencies below, which are what job descriptions ask for and what the GAGE credential records. Every link here is drawn from the same careers map that builds a role's readiness check.
Recognizes AI-enabled fraud, from cloned voices and synthetic video to romance and investment scams, and knows the one move that breaks the script.

How job descriptions say it
Postings rarely use the textbook word. These are the phrases the careers map reads as asking for the competencies above.
Where the frameworks place it: FTC guidance; FinCEN elder financial exploitation advisory.
One interview question about it
A caller sounds exactly like a colleague and asks for a transfer. How do you tell a voice clone from a person, and what is the rule?
Asked of candidates for deepfake, voice-clone and scam recognition. Answering it in your own words is exactly how a GAGE topic is passed, and the credential records the pass where an employer can check it.
If you come from another field
Some backgrounds already carry this competency, and the readiness check gives credit for it.
- Elder services, social work, banking front line and fraud teams carries it as a claim to back up: Fraud patterns are familiar; the synthetic versions are new.
