Unusual voicemail quirks like that extension message often signal automated systems dodging direct contact. This setup screams potential spam or scam attempts, where callers use fake extensions to seem legit while avoiding callbacks. Don't share personal info if they ring again—hang up immediately. Block the number on your phone to cut off future nuisances, and report it to your carrier or sites like 800notes for community alerts. Staying vigilant prevents headaches from these sneaky tactics.
A number rang me; when I returned the call, the line said extension 1502 isn’t taking calls at the moment.
