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 core defense against voice-based impersonation of any kind.

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)
